Pyrokarp

Pyrokarp gets +1/+1 as long as you control a Mountain, a Swamp, and an Island.
{g}: Pyrokarp deals one damage to target creature
with flying. If you control a Mountain, Pyrokarp
deals that much damage to the creature's
controller. If you control a Swamp, that
creature's controller loses one life. If you control
an Island, tap that creature.
It's more than it appears to be.
