Eredin, King of the Wild Hunt

Menace, Haste, Ward — Pay 3 life

When Eredin enters the battlefield, create two 2/2 black Wraith creature tokens with menace.

At the beginning of your combat step, if you control three
or more Wraiths, you may exile target creature.

Whenever a creature an opponent controls dies, that player mills two cards and loses 1 life.
