Shadow essence is a top priority, as is a way to find it. Shadow word pain is consistently good for early drops, though spirit lash is good versus the aggro decks.
Muck Hunter can be decent at picking at boards when you eternal servitude him or shadow essence him. There’s nothing like y’shaarj, quite yet, but he’s pretty good for filling gaps. Best combo is servitude for devilsaur, into double vivid nightmare for 21 burst damage, 18 with leeroy instead. Spirit lash with muck hunter is also really good.
