Set TB Release & Errata

Tamer Boost (TB) is a small release but with something for everyone. There are 26 new cards; all but 1 are Options. The odd one out is a special Mastery which also opens up a new format possibility for players. There are some rule changes and additions. The big aim with Tamer Boost was to provide as many granular new options as possible, especially type changes and rarely mixed effects. More proxies were also a big priority.

Gem Rule

The gem rule:

  1. At pre-game setup, immediately after you make a side pile, take up to any 4 “gem” symbol cards from your deck and add them to your side pile face-up (showing the gem side).
  2. Opponent can inspect face-up cards. Continue play as normal.

Finally! We’ve been waiting since Gems were first released in Tamer Accessories to reveal their intrinsic effect. If you thought the only purpose to gems was for search cards in Solar Flare and Royal Domain, well I have good news. The rule for gems is they are free before-game, face-up side pile cards!

What this means is, after you create your side pile during the game and your deck is now 40 cards, you may take up to 4 additional cards with the gem symbol out of the deck, place them face-up on the side pile for the opponent to see, and proceed as usual. So decks can now have 36-40 cards during that period, a max difference of 10%.

The aim here is to make certain cards with intrinsically great mid game effects (but less good early game) less able to ruin opening hands at the cost of giving the opponent information. Of course, now that they have the information, it changes how they play, even if you don’t use them muahaha.

Arena Format

As an additional deck legality requirement for Arena Format, both players must use the “Arena” mastery in their Destiny Zone.

New format! Arena DBE is a casual alternative to DBE in which both players add the mastery “Arena” to their destiny zone. With this, the game will feel a lot more like Digimon World: Digital Card Arena and Battle. Both players have open information about all hands and hands refill to 4 each turn, but can’t go higher without triggering discards. This changes the way certain cards can be played and some become better or worse when your opponent knows you can play them. This means threats are live more frequently but bluffing is difficult if not eliminated. Players can of course use the mastery as normal in their own deck.

Shatter change

Shatter effect has changed. The new way of using shatter is this:

  1. It activates at ability speed 1, along with things like Counter and Grudge.
  2. When it activates, reduce opponent power by own (Shatter) attack’s printed power.

That’s it. No more on-hit effect, no more attach destruction. Since the EX release of Shatter, it has always been the odd ability out. This is because it was combined from two separate abilities: reduce power generally and remove attaches. The original concept just needed a few modifiers to work but it took way too much time to test such a big fix and so here we are. Printed power was the way to go all along. It may be surprising to find out it took so long to nail that down, but Shatter is actually the combination of every “Guard” ability smashed into one and made fair! If each Guard were in one effect, it’s just a free turn for you, as your opponent normally does nothing with 0 Power. An early idea was to halve all power but that’s actually stronger than a Digimon support by itself, and Cross abilities shouldn’t be stronger than a Digimon support innately. Exceptions like Drain are “costed” more heavily when I create the cards and thus reduce other stats. Another was to make it always reduce -200 since that’s the general level of this kind of ability but that was too inflexible. It’s more challenging but more rewarding to design with the scaling effect of more power means more reduction. As you probably noticed, Shatter was heavily reduced in power because of its drain-like defensive results plus removal capability all in one. The problem with the on-hit requirement was needing 1st Attack to be paired with it for maximum viability. Otherwise, it just existed as generic removal, which is pretty boring as an attack ability goes. Abilities are meant to add dynamism to the game, not take it out. In the case of Shatter, it’s already a player’s bid to not have to think too hard about what attack the opponent chose, so we stuck with that and honed it correctly.

Eject keyword

Meaning: “Remove the specified number and type of cards in play from the specified player (1 of own if not specified).

They go to the trash as usual but is not counted as trashing. Since Shatter was changed not to remove attaches anymore, new cards will be created (some exist in TB) which remove attaches, especially the opponent’s. But because in the past we have used such inconsistent wording (discard, trash, remove…) for this process, it causes confusion as to whether they actually count as discards or trashes or whatever, for the purposes of Heracleskabuterimon and other effects. They were not intended to count for this. Attach removal was always supposed to supersede any other effects dealing with discard or trashing. From now on, when cards are taken out of play and naturally either put into the trash or deleted as a result, they are “Ejected”. This is mostly for attaches and DP cards. We will now stick to “discard” as meaning the hand and “trash” as meaning to the trash (from the deck).

Errata Oct 2022

It’s a small release so the errata are here:

  • Lucky Mushroom ➤ Art, name is Happy Mushroom (Digimon World 1, DCA mistranslated from Unlucky)
  • Silver Ball ➤ Art, removed opponent discard
  • Behemoth ➤ Art, effect trimmed for adjustment to Shatter. Ejects attach or power.
  • Metalgreymon ➤ Art tweak & general template power text size increase (done because Arena art uses upgraded card frame)
  • Vending Machine ➤ Art, simplified to BR-only effects
  • Data Copy ➤ Art
  • Uninstall ➤ Art, trashes 10, draws 2 on fail

Promo — Heavyleomon

Remember those promos for Cyber Junk? Well there’s one thing we couldn’t do at the time that we really wanted to. Heavyleomon! Yeah, its model was totally broken at the time but now we have obtained the power of 3D modeling and rigging. So please enjoy Heavyleomon with the new template. The purpose of CJ was originally to be the supplement expansion to XD, but the Zuba models weren’t fully ripped and available yet so we moved on to the rest of the PenZ Metal Empire. Heavyleomon is from PenZ:ME so now we finally have a conclusion to Loaderleomon sitting alone. You might notice some excessively good use with Loader!

Well there’s still no Locomon but look at Duramon and…is that Piledramon??

Sep 2022 Errata NEW template

Auxiliary Set Release — XD

  • Finally, it’s here, XD! The D is for Durandal. Auxiliary sets are even smaller than mini sets, typically around 10-12 cards. These focus heavily around a central theme—in this case, Zubamon & related blades. These sorts of sets are really great for adding small supplements to the game in a way that’s easy for us to design and develop over a shorter period of time. The effects in this set focus on hooking a benefit into your own KOs and keeping your DP zone filled enough for a comeback. So it charges down like a train, gets a huge hand and keeps coming when knocked back. It’s relentless! XD is also the premier of our new card template! This is so exciting. We can’t wait to have people dive right in and start having a blast.

Royal Domain Set Release — RD

Royal Domain
  • Huge set! Very very exciting! Royal Domain is a big set we’ve been planning for over a year now which is meant to add a lot of Level M cards to the game as well as Aces. Since these cards are only 1 per deck, they tend to get low priority in most sets and have 0-2 of each. But rule of cool: If it’s cool, downsides be damned, just make it. Even if you’re not likely to see your Mega in a given game, we still worked to make each one feel unique and powerful, besides the fact they compliment play styles in the game.
    • “62” New game cards
    • 12 New Options (2 Proxy)
    • 1 New Mastery
    • “46” New Digimon
    • 3 Evolutions
    • 2 new Flip cards
    • Mimic ability returns
    • Nova counters return
    • 2 cards attach
    • 6 Ace cards
    • 2 Firewall cards
    • So many Megas!
    • Shiny things! Chess!

As the word “Royal” implies, this set contains a few missing Royal Knights like Sleipmon, Dynasmon, Lordknightmon. The total number of  Ruler Digimon and cards for them have gotten a big boost. But of course—this is Royal Domain. We didn’t neglect the other stages of evolution and there are plenty of Rookie cards with a second printing now. No new Datas, we’re sorry :( but we made a playable Venusmon before the official card game! This set took a lot out of us, especially the development phase, so we hope you enjoy.

Solar Flare Set Release — SF

Logo for set SF with Shinegreymon and Burst mode
  • Another followup set, this time for XC. Before, those murky bunnies got the followup Lunar Eclipse and now the burning cats get Solar Flare! You see what we did there? These follow-up sets are meant to flesh out their partner Auxiliary set (in this case, XC) and have about 15 cards. These are themed but less so than Aux sets in order to bring more variety. There are actually 3 new mechanics in this set, which is probably a record for something so small. The attack ability “Mimic”, the keywords Fast/Slow, and the mechanic Nova counters. We had a lot of fun making all these new cards so we hope you have as much fun playing.
    • “18” New game cards
    • 4 New Options (1 Proxy)
    • 2 New Masteries

Auxiliary Set Release — XC

Logo for set XC with Coronamon and Apollomon
  • And now for the long-awaited third Auxiliary Set, XC! The C is for cats & corona, like the halo of the sun. Auxiliary sets are even smaller than mini sets, typically around 10-12 cards. These focus heavily around a central theme—in this case, Apollomon & related cats. These sorts of sets are really great for adding small supplements to the game in a way that’s easy for us to design and develop over a shorter period of time. The effects in this set allow you to partially mulligan several times in one game and hook into the discards for various other neat effects. This one was super cool to work on and I hope you all enjoy.

What’s this? Promos for Cyber Junk!

The cutting room floor is always full of things with Digimon Battle Evolution. But eventually, some cards get worked out and released as promos! Here’s the 2 that originally didn’t make it into CJ, but are very important: Monodramon (Metal) and the first debut of XV-mon! These aren’t integrated into TTS yet but you can always add them yourself. These are meant to be part of the Pendulum Z metal empire Digimon released in CJ. Please enjoy.

While not a Dragon type, I wonder if it can support a certain Dragon?
Even though it’s not a Dragon type (just like Pendulum Z metal empire), you can treat it as one! Recycle “up to”? That’s a lot more control than Recycle! I guess it can be used with Dracomon for an Ancestry theme…Let’s give him a lance!

Cyber Junk Set Release — CJ

  • We got a new set closely following the release of LE called Cyber Junk—CJ! This set is larger than an auxiliary set, with 26 new cards. The central theme here are mechanical, metal, cybernetic, and digital things. CJ is loaded into TTS now. Enjoy all the cool new stuff! (Full spoiler gallery at the bottom of the post)
    • 26 New game cards (8 Digimon, 15 Option)
    • 2 New Attach
    • 6 New Aces!
    • 2 New Masteries!
    • 2 Level M
    • New Data

Designers Notes! (Don’t peek)

The reason for this set was originally to expand the number of options in a small collection that would also include some new Aces and masteries. This was for the purpose of game population. But since masteries take so long to develop (due to their complexity), there was time to create even more cards and the set went from being a handful of new options to something with many Digimon as well. The options were originally going to focus heavily on the gear of Digimon, such as Psycho Blaster, Trident Arm, Mugen Cannon, Mega Hand, and others were added over time. We wanted the new Ace cards to reflect some signature move of the Digimon, especially Metalgarurumon and Wargreymon. If you pay attention closely, Gaia Force and Grace Cross Freeze give you the power of those Digimon from their Level M and Data cards! With the Digimon, there’s a clear vehicle theme in this set which we tried to stick to and only branch out when necessary. Here is something special about some of the Digimon:

  • Junkmon was an early addition because we want to release as much of the PenZ Digimon as possible. His effect helps you rebuild!
  • Nanomon was also meant to be a part of the set in an early design list from last year, as it was one of the original V-Pets not yet made into a card.
  • Rebellimon sports a new type of evo-bonus we are introducing, that works like type resistance. The opponent will lose power if they are of a certain type!
  • With Grandlocomon, the opponent gets hit by a train. OOF.
  • New Raremon is much stronger than the old and can trade relative HP for flat HP! Use it wisely.
  • New Tankmon is made with an effect that gives a lot of power of course. But just in case you get KO’d, you get cards too.
  • Loaderleomon brings a new style of giving tribute to the opponent, instead of only self-sacrifice. What a nice gift of DP!
  • Darkdramon is unaffected by sacrifice and just wants to win. He’s an elite fighter that will use any trick to beat an opponent and is very strong.

In this set, many of the metal Digimon have their normal sacrificial effects and some of them have ways to recover HP. This allows newer players to try the metal style without feeling like they will necessarily lose.

I wonder what would happen if a Mamemon used Smiley Bomb?

Did you notice Tigervespamon’s “Royal Meister” grants the same bonus as the unopposed victory bonus? Mach Stinger V (for Victory)!


Pop these into your Destiny Zone when building your deck and for the price of 1 card and whatever downside is printed on the mastery, you get access to a constant bonus during the game.

Laplace Like the demon of the same name, you’ll start to know everything with immense draw power, provided that you sacrifice your health for it…Unfortunately, this means you won’t be able to use attacks that preserve health! Steel yourself with the spirit of Laplace.

Calamity Put a permanent end to your opponent’s deck or get more trash conversion. With this kind of alchemy, you can zap everything away with the spirit of Calamity. But the opponent recycles to thwart your plan…

Lunar Eclipse Set Release — LE

  • Finally it’s time for the followup set to XB, Lunar Eclipse! The light of the moon and shadow of the eclipse—a classic contradiction of light and dark plays out in Set LE, as Set XB wanes. Like an Auxiliary set, this is a small set, with 15 cards. Also like Aux sets, this focuses around a central theme—in this case, light and dark. It’s a small supplement that’s easy for us to design and develop over a shorter period of time. The smallness coupled with the focus on themed effects should make them feel special. LE is loaded into TTS now. Enjoy all the cool new stuff! (Full spoiler gallery at the bottom of the post)
    • “15” New game cards
    • 2 New Options / Attach
    • New Ace
    • 2 New Masteries
    • Dark Draw/Trash/Discard returns!
    • Attack ability “Killer” returns!
    • Flip cards return!
    • New special Flip cards that change to an alternate, powerful mode.
    • “Access” keyword returns!
    • Long-awaited Cherubimons and Marineangemon!


Pop these into your Destiny Zone when building your deck and for the price of 1 card and whatever downside is printed on the mastery, you get access to a constant bonus during the game.

Lunar has art depicting a glowing Moonmillenniummon and is intended to let players Corrupt (up to 3 per turn) by making cards enter the dark area. The downside is, whatever amount of cards you would normally just draw during the Prep Phase, you’ll have to wait until the end of the Prep and they also end up dark drawn, so it’s slow! But, that means cards enter the dark area…Don’t forget your first draw of the game is also dark draw and corrupt; and any attaches that draw during the Prep Phase like Purity Crest.

Eclipse shows a shadowy spirit of darkness and lets you always support face-down! You won’t need to attach Hope Crest as often to control the game and get inside the opponent’s head. However, you are no longer allowed to support from your deck (normally face-down) nor from effects (from either player)! Be careful not to rely on cards like Hacking, Aegisdramon, and don’t run out of cards for support—you won’t get to dig for more. This also won’t have a tremendous use on your own turn.

Flip cards Return

You can check out a detailed explanation on the accompanying post Intro to Flip Cards. Pay attention to Lucemon and Marineangemon: these two are special flippers that don’t operate “normally” to provide an alternative card which was the case with Antiramon and Dianamon in Set XB. These achieve some sort of goal to reach a much stronger mode of the card by flipping into a Ruler Digimon! You can also check all the flip cards at the bottom of this post.

Killer, Access, Dark Draw Returns

Killer – When the opponent uses the attack specified on the ability, you get 1st Attack and Boosted Power of +300. Kind of like a lightning-fast version counter attack that’s a bit riskier since you still take full damage when you’re hit. This resembles the Gem cards that were released in set TA.

Access – Show a card from your hand to your opponent, as specified here; usually a type. This is a cost, so it’s optional but you won’t access the following effect unless you do.

Dark Draw – Dark Draw (or Discard) will place that card from your deck into your Dark Area (or from hand to DA if discard). Dark Area cards are added to your hand in the Prep Phase after your normal draw.

Large January 2021 Errata

Tabletop Simulator now has all the erratas and set XB! So the set release is no longer just window-shopping. TTS also has the blue player hidden zone fixed, since that was quite an error. Try using the new “spread” feature in Tabletop Simulator on the Masteries, it looks rad. Below is the gallery for all the errata art fixes that we made. Some arts were also changed to stock renders just to spare everyone’s eyes while we work on this art replacement project.

We also released a keyword called “Access” to replace the long text “Reveal a [card type] in hand:”, so you can find the exact details now in the rules.

Special update! XA has had 2 cards added to it. That’s right, this game is completely digitally distributed so I can do whatever I want, including release cards for older sets. Truth be told, they were supposed to be in there anyway but Masteries weren’t fully tested by that time. So it’s basically cut content being patched back in.
