X, Twisted Trickster

Flying, First Strike, Hexproof (against being controlled, getting exiled, and/or destroyed.)

Whenever X kills an opponent’s card, exile it
and make a token copy of that card under your control with a -1/-1 counter on it, if the copy’s power or toughness would equal 0 instead of making a copy of the card, draw a card.

“SO MANY SOULS TO PLAY WITH, SO LITTLE TIME.” - X
