Deepwood Sovereignty

When Deepwood Sovereignty enters the battlefield, exile target creature you control until Deepwood Sovereignty leaves the battlefield.
Creatures you control get +X/+Y, where X is
the exiled creature's power and Y is the exiled
creature's toughness.
The titan simply stared, and the vermin littered across
the forest floor began to stir, and surge forth like a tide
of death from the darkness.
