Oil Covered Horror

When Oil Covered Horror enters the battlefield,
you draw X cards and lose X life, where X is the
number of nontoken horrors you control.
Other horrors you control get +1/+1.
Since the invasion several of the fleshy organisms
have been corrupted by Madiche. They wander the
plane in agonizing pain, unconnected to the rest of
the world. They simply scream.
