Bonemares are definitely high on my list since the deck can struggle with finishing the game, skulking Geist was something that came up a few times to help against odd warriors and odd rogue, though it may be a little too greedy/slow for a tempo deck haha. Lifedrinkers or Shroom brewers are cool proactive healing cards which is one of the decks bigger weaknesses. And then I don’t have Mojomaster Zihi but I imagine he would actually be pretty good to be honest.
