Well Wild is a format that blizzard at least endorses a bit thats why the nerf/ buff stuff that only effects wild. Im not saying that they have to balance every new card around every old card but at least try not to break the entire format with a broken new combo. Also idk about you but i think auto win turn 6 is kind of broken. The Wretched Tiller combo cost more mana and required more cards and it got hotfixed so im pretty certain the same thing will happen here.
