I feel like it's too slow for this deck. By the time I'm dropping 5cmc my hand should be fairly low from casting ctrl/cheap zombies and i'm going to want to be dropping Curse/Geth/Grimgrin. Being able to drop a top decked zombie for free wouldn't be too beneficial it seems in the 5 spot. Though it would leave more mana open to activate drownyards each turn.
Edit: oh, storm's a 6 drop. Definitely seems too slow
