it has so many ways to keep its hand full with spirit echo, mana tide (+ tons of taunts), and servant of kalimos that it almost never runs out of threats like many other tempo-ey decks do. It can get boardcleared over and over and just keep filling up the board without even running out of cards. Its not making particularly weak boards either.
in my experience its very strong and very underrated. I'd encourage all of you to give it a try.
Love this deck. I always fall into the trap of trying to make Ozruk work. It usually doesn't, but sometimes I make a 5/40 taunt and cackle to myself.
