Stream thoughts below, split up by line. The Druid overkill card is pretty decent - maybe not broken enough for constructed, but its high power, and maybe fits in a big Druid with Gloop Sprayer? Oondasta looks fantastic - theres the obvious Hunter synergy, allowing you to fix any beasts you draw early in a Kathrena deck, as well as Zombeasts. Druid and maybe Warrior could have some synergy too. Theres also just generic synergy with Charged Devilsaur and Witchwood grizzly. Shaman legendary is fine, doesnt seem like one Id be disappointed to pull Mage hero power package seems like its potent if you can get it to go off all at once, but thats a lot of low power cards for not a whole lot of payoff. The Spirit making your hero power into shooting star seems overcosted but maybe fine against aggro? They finally printed a discolock payoff card! I still dont think it will be any good. 1 mana/discard/2 damage whirlwind is nice too. If they print a low cost card that does things when discarded I might be convinced though.
