Night King, Raiser of Dead

Flying, Menace

Whenever Night King, Raiser of Dead enters the battlefield or attacks, each player mills 3 cards.

At the beginning of your end step, for each player,
choose a creature card that was put in their graveyard
this turn. You may put those cards onto the battlefield under your control with an Ice counter on
them. They're Zombies in addition to their other
types as long as there's Ice counters on them.
