Overlord of the Balemurk (PPDSK-113) [Promo Pack: Duskmourn: House of Horror Promos]

Impending 5—{1} (If you cast this spell for its impending cost, it enters with five time counters and isn't a creature until the last is removed. At the beginning of your end step, remove a time counter from it.)
Whenever this permanent enters or attacks, mill four cards, then you may return a non-Avatar creature card or a planeswalker card from your graveyard to your hand.
