Eyepocalypse Swarm

Flying; trample
When Eyepocalypse Swarm enters the battlefield,
create a number 1/1 black eye creature tokens
with flying equal to the number of cards in all
opponents' hands.
Sacrifice a creature: Eyepocalypse Swarm deals 1
damage to any target and 1 damage to you. If that
creature was an eye, draw a card, then discard a
card.
