Grubdug, Never Gorged

Trample
At the start of combat, destroy the creature with
the highest power amongst creatures on the
battlefield. Grubdug, Never Gorged gains power
equal to that creature's power until end of turn.
"Grubdug wished for too much. He was too greedy.
Now look at what he's become. He can't even talk
to us anymore. He's too busy chewing..."
