Geddith, Deepwood Horror

Grisly - Whenever a creature card leaves your graveyard, destroy target creature with power
less than that creature card's power.
Delirium - At the beginning of your upkeep, mill
two cards. Then, if there are four or more card
types among cards in your graveyard, return a creature card from your graveyard to your hand.
