Auxiliary Set Release — XB

Finally it’s time for the second Auxiliary Set, XB! The B is for bunny. Auxiliary sets are even smaller than mini sets, typically around 10-12 cards. These focus heavily around a central theme—in this case, Dianamon, er, bunnies. 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 smallness coupled with their focus on themed effects should make them feel a bit more special. This is my way of making somewhat linear evolution trees more palatable. I think there’s some cool new stuff in here and I hope you all enjoy.

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 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.

Intro to Flip cards

In Auxiliary Set B, Dianamon and Antiramon introduce the concept of flippable cards! Flip cards share a card number, so they’re the same card for deck building purposes, but can flip under various conditions within the game. Some will start on a specific side and others will have freely choosable starting sides. Check the other tabs for what the new icons mean and how flips cards work.

The Star side of a card indicates one possible face that it can be flipped to or from. It’s distinct from the moon side. It’s not necessarily the initial side of the card and if so, is indicated by the Initialize icon.

The Moon side of a card indicates one possible face that it can be flipped to or from. It’s distinct from the star side. It’s not necessarily the initial side of the card and if so, is indicated by the Initialize icon.

If this card starts in play, such as in the Destiny Zone, then Start of game: Place this card with this side face-up.

This initialize icon indicates the card’s “face-up” side. The accompanying icon to the right of it is the card’s initial side (star or moon).

Cards may not have an initial side and if so, will not have this icon. Those cards generally start the game in a hidden zone such as the main deck, where they should be hidden.

In all cases, a flippable card that enters a hidden zone MUST become hidden. It does not show a side in a hidden zone (e.g. hand, dark area, main deck), even though it is a multi-sided card.

Cards without this icon can still be flipped.

In deck building, be sure to respect the normal rules about a card’s unique card number and card limit caused by that unique identifier, same as you would do for any other card. Example: You may have XB-006 Antiramon [Moon] as the card’s initial side OR XB-006 Antiramon [Star] as the initial side because neither have this icon. And among those, you may only have a total of 4 cards. You could have up to a total of 2 of the [Star] and 2 of the [Moon]; or up to 3 of the [Moon] and 1 of the [Star]; or any combination up to the normal card limit. The sides can only flip after the game starts when an effect instructs you to. Before a game, players are normally allowed to change any cards in their deck and that includes choosing the initial side for cards without this Initialize icon.

This icon is a stand-in for the keyword “flip”, which means to turn the card over to its other side. It may be accompanied by a side icon, in which case flip to that side if able. It may be alone; if so, simply flip the card to another side only-if it has a different icon on its other side.

Cards without a side icon cannot be flipped.

Cards with a side icon can only be flipped to a card with the exact same card number with a different icon.

Example: XB-003 Dianamon [Star] can flip to XB-003 Dianamon [Moon] because they have the same card number and different side icons.

Flip is considered part of an effect or cost, and therefore a process that a player performs (like Trash, Discard, or Draw). By default, Flip targets your own active Digimon. It may target the opponent’s active if specified (or uses “any”). It may target a card in the Destiny Zone or attached if specified. In all cases, the card flipped must be somehow in play (i.e. in a “zone”).

Flip is always considered to have the rules text “if able” after it.

You do not flip cards face-down unless the effect specifically states this. Unless an effect says “Flip facedown”, the back face (hidden DBE logo face) of a card should never show after a flip.

Flip cards are unique enough that they may create some rules confusion. Check this section for how each interacts within the game rules.

Flip card numbers are the same but their names may be different.
In XB, there are no differently-named flip cards. “New Moon” on Dianamon and “Deva” on Antiramon are just flavor text to help players talk about the cards uniquely.
When naming a card due to a card effect (e.g Fated Spirit), simply name any valid side of the flip card.
If a flip card is the active Digimon, the other side is not considered “in play” for any of its unactivated effects, power, attack abilities.
If a flip card is the active Digimon and has a permanent evo-bonus active, then flip to another side, the evo-bonus will remain active because the card did not change from the active spot. It only flips over.
When flipping a card at any time for any reason, update all the info about that Digimon that is not permanent or changed by effects. For example, its printed powers, types, attack abilities, passive effects, and available “Activate” effects if any will now be available or unavailable depending on whether it is the visible side.
When flipping a card, do not update information that has changed due to an effect or is permanent. For example, do not change the HP, any activated permanent evo-bonuses, or the status of a used “Activate” effect. Do not remove any floating effects that modify the active either, including Power boosts, attack ability changes, or changed attack selections.
Flipping an active Digimon doesn’t count as changing which Digimon is active, doesn’t count as a KO, doesn’t change any chosen attacks, doesn’t cause it to become abnormal.
If an active Digimon flips, even though its types may be different, do not count this as “changing” a type. Example: Antiramon [Star] was Wind and Nature types, but changed to Dragon by an effect. Later, it flips to Antiramon [Moon] and its type is now Nightmare instead of Dragon. This does not count as “changing” to the Nightmare type.
If a card flips multiple times during a turn, be sure to update it multiple times.
Players may check any side of a flip card at any time while it is in a non-hidden zone.
During the evolve phase, when activating the evo-bonus of a future, if that future is a flip card, only activate the bonus of the current side. If another effect flips the Digimon before you could activate an evo-bonus, the same rule applies and you would activate it on that new (now current) side.

Try it out for yourself. Click Dianamon and you’ll see how she flips between different sides.

Mini Set Release — Tamer Accessories

Tamer Accessories (TA) is a small, but not auxiliary set that brings you lots of new Plug-Ins to CARD SLASH into your Digivice! Not to mention Chips…
- 20 New game cards
- All Options and Evolutions
- New mechanic & keyword: Dark Area (Dark Draw)
- 7 Proxies
- 1 Ace
- 4 Evolutions
- 12 new Plug-Ins with support for the type
- 5 new Chips
- New Gem type cards?
Trivia: There were secret breadcrumbs for this set in several pictures posted to the Discord and even a full card preview of Reload Plug-In Q with advice on how to use it for a changed Plug-In Backup article.
What is Dark Draw?

A new temporary zone is created when players use a dark effect. The “Dark Area” is like your hand, but you can’t use it yet! It’s a hidden zone, same as your hand is for your opponent. After the draw step of your own Prep Phase, you must take everything in the dark area to your hand. So cards that dark draw on your own turn are in suspended animation for a whole turn, but if you dark draw on the opponent’s turn, you can safely draw cards without interfering with your draw step’s hand count. Hi-Speed Plug-In B has an extension of this mechanic called “Dark Discard” where you would discard 1 from hand to the dark area, essentially robbing you of it for some time, but also protecting it from other hand removal.

Note for Tabletop Simulator users: Please use “Peek” button for Dark Draw, since it sends the top 1 of deck to a hidden zone.

Small December 2020 Errata

Tabletop Simulator now has all the name-changed erratas as with the previous post. It also includes a permanent token so you can denote when your active gained a permanent effect. There are 2 bugfixes: Terriermon should’ve prevented duplicate activations of its evolution effect, since it’s intended to be the equivalent of putting its name in all those boxes. Another bugfix: wrong version of Hacking was sent out in the big errata, that draft was tested and scrapped immediately. The final is below, and has HP changing. Artfixes: Monodramon, Metalgreymon, Cherrymon, Cherrymon’s Mist! Artfix with an updated effect: Snowgoblimon! FINALLY. If you don’t see new images, refresh the page.

NOT replaced in TTS (trivial): Ebemon, Purity Crest

Digimon COTD: Toy March

Toy March Digimon Battle Evolution Option card

Toy March—They just keep going…and going…and going…

What’s good about it: You pick one of any 4 effects that stay permanently for the game. The flip effect means no need for Gazimon. This benefits the need to know what card comes next (for either player), for use with cards that lock powerful effects behind that knowledge, plus your own ability to have an extra card for support, and never be surprised by a cornered opponent who uses a top-deck support. The hand reveal effect means no need to attach Research. Opponents who keep large hands will have a hard time surprising, and changes the strategy phase to remove risk. The draw 2 effect relieves the burden of needing Purity Crest attach or similar. This keeps a medium or high hand staying high all game. The max hand limit remover means not needing to evolve to Jijimon, Ebemon rapidly. High-hand or conservative decks can continue to accrue better possibilities without hitting a wall. Read more

Digimon COTD: Bigmamemon M

Bigmamemon—One bean to rule them all…

What’s good about it: There’s so much. Their HP is at 2600—a number befitting a massively composite colony of Digimon. Only 4 Digimon have more HP (in order): Zeedmillenniumon, Moonmillenniumon, Plesiomon, Olegmon. The first two are dimension-shattering time gods who are DNA-only. The latter two are the upper-limit of the highest-HP type in the game: . The Power distribution of Bigmamemon is also comparable to these same 4 cards, which says something for its status as the god of beans. Notably, everything else close to Bigmamemon costs 70 DP or is DNA-only (Millenniumon, HiAndromon, Diablomon, PR Herculeskabuterimon). But it goes beyond such wearisome comparisons: Bigmamemon has two passives. The bubble number ① effect is available during the support phase and is just a built-in TOY Missile Pod. No need to worry about attaching it! For bubble number ② (the cyan color just sets it apart for you), you passively void all cross abilities with “Circle to zero”. This is really mean. A mean, bean, machine if you will. Bigmamemon already has one of the highest HP in the game and once the ② effect is accounted for, it probably has the highest longevity ratio of any Digimon, since you can swing at full power with huge HP. The cross ability can even stop x3 VS (cross power to 0), assuming you used Dominion to take on a vulnerable type. If that’s not enough for you, it has one of the highest-potential for abuse evo-box bonuses in the game: “Get all below this”. Read more

COTDs updated for errata

After this 2020 November errata, I faced a lurking problem: old Cards of the Day. They were no longer accurate! Now they are. I’ve gone through all the cards which were changed and also had a COTD to change all the pros, cons, tips, and various combos and considerations. It was exhausting work, and I haven’t even checked the other COTDs to see if they reference combos with errata’d cards. The work was even harder since I expanded every article, much of which were considerable additions. One major difference—every significant card that was referenced in the old articles uses the new card-preview feature when you hover your mouse. Now you don’t need perfect, librarian-level knowledge of the game! Let the research begin…

Articles changed (click for the article):

Millenniumon Chimeramon art and name rework

Minor update—new arts! Today, I spent some time lovingly recrafting everyone’s favorite composite world-enders. Chimeramon and Millenniumon also have name changes: Kimeramon, Chimeramon, no real difference there, just making it easier for some to understand what it is. Millenniumon’s change removes a duplicate ‘m’. For the longest time, that MM was all I could find for the official name, but it doesn’t match with the pattern of Zeedmillenniumon or Moonmillenniumon, so that’s fixed. No worries about updating your Zeedmillenniumon deck: the correct name was already in the evo-box and the DATA card was also fixed.

With these art and name changes also comes a few tweaks. Chimeramon now has DNA from any + instead of Airdramon + . This should impact almost zero decks, since the primary use was with its other DNA set. Now you can finally use Garurumon, Devimon, Kabuterimon, and Kuwagamon! Millenniumon also got a tweak or two: the triangle power and cross power have been swapped to prevent 1st Attack domination; its circle-to-zero addon ability was replaced with cross-to-zero, both to prevent its already huge lead and spice the game up more in case someone takes advantage of one of its many types for x3 VS.

Chimeramon’s name change affected these Digimon’s evo-box: EBEmon.

You can use these immediately in TTS, though they are not updated. Please simply upload the cards and resize them for your deck. For EBEmon, you can skip the extra work and just treat the name as “Chimeramon”.

Last errata update had a couple of missing name changes. I’ve fixed that post but here they are again just in case you missed them: Cupidmon, Holyangemon, Purity Mask, Megalogrowlmon, Deathmeramon, Plottmon. All of these except Purity Mask are correct in Tabletop Simulator.

Errata Nov 2020

Big November 2020 Errata

New design philosophy permeates this year’s big errata. There are literal hundreds of erratas, many for effects, balancing, styling, evo-boxes, and especially art. This time, I won’t be able to list them. Instead, I’ve prepared a set of highly important changes plus some new art samples. By the way, the Tumblr had explanations of these art while we worked on the release. So if you don’t know, the VMundi Tumblr is where we do the “making of” and let our hair down a little. Check it out. Now that we can do a lot of much better, more expressive, higher-fidelity, and more varied art, the game will be shifting focus in that direction. There are 3 types of errata showcased below: changed identity (name or concept), art synchronization (to the original PS1 concepts), or upgraded art, usually from something bad or randomly found.

The all-important identity changed cards have name changes, which is very important. Consult this list so you’re aware of these changes. This is similar to the “Mugendramon”, “Atlaskabuterimon”, et al changes before.

TOY Set Release

The first medium-sized set in almost 2 years! TOY marches in 50-cards strong, packed with new strategies, tough choices, a new card type, and new mechanics.

New Promo on Samhain — Mystimon

Yesterday, I hinted that the pointy hats may not be over. It’s still Samhain, so let’s go. Stepping over the hedge of the Otherworld as a complete wizard, Mystimon makes its appearance! Mistymon? Mysticmon? Whatever, it’s mystical and from Witchelny! Let’s dive right into the new stuff it has.

Evo-box first: The odd thing you may notice is “Wi-mon” and “So-mon” both Level C. The rules for quotation names is that you substitute the “-” part for anything or nothing. So “Wi-mon” for example would be Witchmon or Wizardmon. If it had “Devi-mon”, then Devimon and Devidramon work. The actual permanent effect allows you to change its cross ability every Strategy phase, right at the start. You can pick from any attack ability in the DZ. So if you had BIT-006 Hyogamon in there, you could change your ability into Counter (of course, your Power is now 0 as usual). Bear in mind, that change is a lingering effect and will dissipate at the end phase. But this works to your advantage in case you want its x3 VS back! You can always pick another ability next turn. Here’s a list of what Digimon exist that you can use this with:

Witchmon
Wizardmon
Soulmon
Sorcerymon

All with pointy hats of course. Rulers can’t evolve from normal types, so using names is necessary. Don’t forget they also can’t be played as Abnormal (hence no stat block).

Support effect and Active effect: You may notice some odd stuff going on here. The bubble number ① and ② were added to help with clarity because its box is a bit confusing without them. Both the numbers and the cyan text denote a break in effect. If you SUPPORT, you get ①, and both players will have their power become the same as their HP. Basically, more powerful Crash but…for everyone. So play it at the right time. This is very much the feeling of Nightmare effects!

For effect ② (cyan text), use this from the Active spot like any other Passive ability. When your active is Mystimon, you’ll be able to Discard 1 Option as a cost to then draw a different option from your trash. Spellcycling! You can only use this during times on your own support phase when you can play a card though, so right at the start of the phase and when you are supporting that turn too. Try to think of some interesting combos and bear its limitations in mind.

If you want to know the interesting story behind how I did this art, tumblr post.
