Emperor Emhyr var Emreis

Hexproof
As long as Emperor Emhyr var Emreis is present
on the battlefield, all abilities that restore a card
from the graveyard, including your own, target
a random card.
{x}{t}: Play a card from your opponent's grave-
yard. X is the target card's total mana cost.
They do not call me "the Patient". Take care they do
not call you "The Headless".
