Vecna

Indestructible
At the beginning of your upkeep,
you may pay {2}.
If you do, you draw a card and you lose 2 life.
At the beginning of combat on your turn,
Vecna gets +X+X until end of turn,
where X is the number of cards in your hand.
At the beginning of your end step, if you lost
2 or more life this turn, create a 2/2 black zombie
creature token.
