Haskell, Steward of Kroxa

Haste, Menace, Deathtouch
Each creature card in your graveyard has escape.
The escape cost is equal to the card's mana cost
plus exile three other cards from your graveyard.
Whenever a creature you control escapes, each
player discards a card.
"Kroxa is insatiable, but not inscrutable. You'll be a
fine meal."
