Ooma

Enrage: — Whenever Ooma is dealt damage,
put the top card of your library into your graveyard. If it's a land, put it onto the battlefield tapped. If it's a nonland card, Ooma deals damage equal to that card's mana value
to each opponent.

"Ghastly, eerie creature made out of thick liquid.
You can peer right through them, and can't see where they keep their thoughts. I don't trust them at all. Keep away." - The Hunter
