@Scarifari dunno... the opponent gives the other play the card on top of his deck
or something similar though i suppose even if it worked like that chances are the card is going to be useless for the card stealer
while im at it i'll just drop another few weird concept cards
? attack / ? Defense Flip: This card gains the name,attack,defense,and effect of its attacker
Flip: Your opponent checks the top card of its deck. if it is a monster summon it on his side of the field, if it is a spell/trap put it into play on your side of the field.
second one is a heavy drawback so i gave it no starting stats because i don't know what would harbor this type of drawback
