You have to press "Send" or "Tick" to first populate the game after loading the page.
All user-input happens in the UI box at the top.
If you need to choose something (which effect, which target, to block) it'll be in that same list.
The game will auto-play all the rules quickly, and you'll see the endstate on the board while it pops up messages saying what happened. This is probably more user-friendly than before when you had to manually 'tick' each step of the game.
You may still need to press "TICK" once certain places to move the game forward. Basically, if "TICK" is blue, press it or else answer the waiting question.

The egg zone will have a pixel-art background, if it exists. The trash will have a black background, if it exists.

You can't see your security or deck, but the lengths are posted in the log at the start of each turn
Because ST15 versus ST16 has no interruptive effects, and those were very important to test, I made up Armormon (Agumon with Armor Purge), and then gave Matt Piercemon (Garurumon that pierces) for balance. OC DO NOT STEAL!!1one

Got that? Great, get started!

There is no mulligan, your opening hand may suck. See below for why.

Set your whole deck

You can describe cards by card ID...

Separate by whitespace or comma, either works.

You can also describe by set and unique prefix. Mix and match!

Player 1 is bot
Player 2 is bot

Creative Mode

Here it is with several challenges.

You can compose a challenge to give to your friends. Helpful for learning those weird edge cases.

Other stuff

If you want to try, open this in one tab and this in another. There's no mulligan right now, osrry.

Bugs

If you try to break the software by messing with the inputs you'll succeed and it won't be interesting. If you breaking the game logic by playing a weird set of cards, that is interesting.

ST8 goldrapidmon's first effect always targets 1 regardless of tamer count
Searchers where you can pick 1 A and 1 B don't currently validate your choices if you choose 2 A
ST17 Henry's Bio-Merge is broken, will probably hold off on this one for a bit
Return-to-hand has 2 bugs: Rapidmon's immunity not applying, and the bounced instance remains able to respond

Each gid uses the same random seed at same start for debugging purposes. If you want it to be really random, start the gid with "rand". If you want both players to have the same seed (meaning they'll get a similar mix of levels, tamers, and options) prefix the seed with "same".
You can reset the game by putting "reset" in the instruction box in the top left and hitting Send.
