Why would Liquid Shadow help? He would be poisoned thus losing 1 Hp a turn and also only heal you for 2 per turn, a dragon is much better for LS than this.
On another note, a good card, I like the idea and yes if it can be used more than once a turn would work brillianly. Remembering in Death you can synergise this with Boneyard and Scavengers thus getting the 2 attack back real fast anyway.
