N’ghathrod, Strongest Horror

Horrors you control have +2/2

If you or a source you control would deal damage to a player or planeswalker, instead prevent that damage and that player mills that many cards.

At the beginning of your end step, choose target permanent in an opponent’s graveyard that was put their from their library this turn. Put that card onto the battlefield under your control. You lose life equal to its mana value.
