There has already been a round of nerfs in the current expansion, a second one is planned in ~2 weeks and there have been some talks about potential buffs too. However, how about some nerf reverts as well? I have a few cards in mind that, although they were a bit too OP and were rightflully nerfed back when it happened, they would be more or less balanced in their unnerfed version today given the powercreep. I am also focusing primarily on cards from classes and archetypes that are bad/unplayable in the current meta and could use a bit of help
Metamorphosis: In its current form it is complete garbage. Reverting the nerf to make it deal 5 damage again might make it playable again. A 5-mana legendary spell should have some strong effect anyway. Priestess of Fury: Giving it again 7 health will probably not be enough to make Big Demon Hunter good, but it might make the card playable in some decks. It would still not be as good as Troublemaker for example Guardian Animals back to 7 mana: I was watching a guy in the Masters Tour yesterday who had the brilliant idea to bring Guardian Druid to the tournament. He had a matchup vs a Miracle Rogue where he ramped on turn 4 and cheated out Animals with Bloom on t6 together with a corrupted Strongman. The Rogue still easily cleared his board on the next turn and killed him a couple of days later. So it seems that a play that was once considered a big highroll that would lead to an insta-win, barely makes the cut as a power play in today's meta and I doubt anyone would find Guardian Animals on 7 mana oppressive any more (Overgrowth on 4 into GA on 5 is kind of similar in terms of power level and stats to Kazakus on 4 into 2 5/5 golems on 5) And finally a neutral card that sees no play: Kael'thas Sunstrider: Keep the cost of the 3rd spell to 1 (otherwise it can really break the game in wild), but I'd like to see him cost 6 mana again. As it is now it is completely unplayable in both standard and wild (although I have no idea who could utilize this card, even at 6 mana)
Uh...kael'thas isn't played in any decent deck in wild, whatsoever. Having the third spell costing 0 would break exactly nothing right now since maly druid (which was the biggest offender on the kael'thas nerf in wild) has celestial alignment and doesn't care about making UI&co costing 0.
