You only need a hydrometer my friend . TRUST me . <| sep |> I ' d say a breath of the unborn . Grasp of Agony is superior in most circumstances to BotU , due to extra damage and 3 mana cheaper in return for a specific range . I would say get rid of the bonereapers for sure , but considering you ' re looking to add hollow grovekeeper , I ' d say it ' s a much slower deck than fastyva . In which case bonereaper will be useful if you can get it to work . Be cautious , as it ' s considered a slow card . Reaper of the Nine Moons is also a dangerous card . Make sure you ' re playing it for stats alone do NOT rely on the dying wish ! Some synergy idea see how well the abyssian card that makes the next minion you play cost only 1 mana works . The drawback to that card is low health , but you can partially negate it with having enough provokes nearby .
