Gorge the Mind

Target creature gets -3/-3 until end of turn.
If that creature dies, its controller puts the
top 5 cards of his or her library into exile and
target creature gets +1/+1 for every creature
exiled this way. If it doesn't die, you gain 5
life and draw 2 cards.
"The Golgari swarm and clear the mind. The empty
space makes a nest for their violence." -Vraska
