It's Not Golgari!

When It's Not Golgari! enters the battlefield,
destroy each creature with a Golgari counter on
it.
{b}{b}{g}, Reveal It's Not Golgari! from your hand:
Put a Golgari counter on target creature.
Just because it's black and green, is rats, has a
Golgari watermark, and uses Golgari counters does
NOT mean it's Golgari!
