Balemurk Overlord Token

This creature enters tapped

Impending 5 — {1}{b} (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.
