it's The Curator's wife! Anyways tutoring effects are almost always high value, and getting three specific draws off one card is bound to find it's way into some deck. Even decks that just want a specific deathrattle will run her, and maybe even tech some poisonous or rush cards like how people teched in Primordial Drake with curator decks just because they could.
Curator had Taunt. And still never really found a deck it fit into that well. This looks a bit worse to me as Rush and Lifesteal are pretty hard asks for most decks. Maybe some deck will just want all 3 and have a need for draw and this will be terrific. I just think it'll end up not being good enough. (like almost every card spoiled in this set)
