You were challenged by a misterious woman to an inocent card game. You clearly should had say no, because just after accepting the two of you were surrounded by darkness.

Now you are in a Shadow Duel, a duel with very particular set of rules that won't end until one of you admits defeat.

You will need to face Spells, Traps and Monsters cards, all of them made to transform and force you into submission. There is some hope though. You also can play this game.

This is Duel Kingdom (everything goes) logic, don't expect a bot to perfectly replicate a card game.
