Olrik, Kos Patriarch

+1: Olrik deals 1 damage to each of up to two target creatures. Tap those creatures. They don't untap during their controllers' next untap steps.
-2: Put target creature card from a graveyard onto the battlefield under your control. It becomes a blue and black Zombie Wall and gains defender.
-8: Look at the top twenty cards of target opponent's library. Exile three of them. You may cast them. Put the rest into their owner's graveyard.
