Hearthpwn

Based on the artwork of the minions hagatha creates they should be amalgams and by that logic count as ALL minion types. It would fit much better into the synergy of Shaman which consistently uses multiple minion tribes.

Another badly needed change is the Azerite Murloc. It's use is nonexistent as it harms any deck that doesn't just want to be a total rng fest. On top of that the payoff of 4 excavate cards is incredibly weak compared to the other classes that can access two azerite beasts. Shaman likely couldn't do that because after playing the first one you'd lose all your other excavate minions.
