Flatten Mechanic

Flatten is a mechanic that was released with set Bit Depth. It decreases the dimensions of opposing Digimon until they shrink into a point and vanish!  On its own, flat doesn’t do any damage or cause any immediate effects—instead, it’s a ticking time bomb. So here are the rules:

  • When you meet your condition (in the pic, opponent used Circle, or opponent’s type is Dragon), you will cause a “flat” to the opponent
  • On attack abilities, only one condition can be met per hit. (If a Dragon uses Circle, it only causes 1 flat, not 2.)
  • Track “flat” by taking a card from the top of your deck, if any, and placing it face-down in front of your active. Neither player may look at it.
  • If you would ever have 3 flats, you get KOd! Shuffle all flat trackers back into the deck. Note, this means you must have 3 remaining cards in your deck to be KO’d by “flat”.
  • If you would take damage while you have the 1st Attack and 2 flats, you get KO’d!
  • When you evolve, you can pay 10 DP from anywhere (such as your DP zone or your Immortalize card) to remove 1 flat marker (shuffle it in). You can only remove 1 flat per evolution.

And that’s how it works. Check the rules for an official explanation (glossary or attack abilities). Flatten is specifically intended as an alternate win method, similar to trashing an opponent’s deck out (which may reduce your required KOs). You will still have to use all your cunning and experience to make the most of it, but it can be a powerful KO method. Since it “poisons” a Digimon, opponents may have to slow down their evolutions. Or you could exploit them after they evolve to Mega for 2 KOs. Repeatedly gaining 3 flats can be difficult, even if you maximize your opportunities, so be sure to have a backup plan.


Term Change: Proxy card

These little “P” symbols used to be called “Partner Options”. Option like choice not the card type. I bet you can see how this is confusing. Especially when DATA and Evolution cards have the “P” symbol now. There’s a new term change—Proxy. It starts with P, it’s thematic, and it’s what you’ll use now! Just a heads-up.

Digimon Battle Evolution is a Digimon card game for two players made by me. Based on the Playstation 1 title “Digimon World: Digital Card Battles” with several changed and updated rules, many altered cards (plus new cards) and completely new game features and concepts. Pick a powerful partner Digimon that easily evolves. Play a deck containing any of eight types of Digimon, or mix-and-match types.

Each player will send out their Digimon, evolve, and support them with their own cards. The Digimon battle until one player achieves 4 KOs! Digimon Battle Evolution is an Expandable Card Game, (ECG) and is free for life. Several expansion sets are currently planned.

Currently the game is completely finished. Organizing a printable version of 300 unique cards (with different printable counts) is quite difficult and has not been completed.




Or search “Digimon Battle Evolution” in the Steam Workshop for TTS.
