Yeah, making it a druid card is definitely the right call here. I'd actually put this at 1 mana... maybe even as a 1/3 but I'd wait for more opinions before doing a 1 mana 1/3 with an upside. As we can see from Lucentbark druid, it is hard to restore health so that is where my justification comes from.
Nice photoshop, btw.
As a deathrattle, this makes this rather slow but necessary, I think, compared to void contract. It's also a strong option against bomb warrior.
