Ruintyrant Oni

Flying, Gorge {3}{r}{r}
When Ruintyrant Oni enters the battlefield deal
2 damage to each creature and player, and sacrifice two ogres you control.
You may pay a gorge cost by exiling X creatures cards from your graveyard, where X is their converted gorge mana cost.
Only when all the ogres are united as one, in one, shall the Great Oni be reborn.
