Remove Deathknights. Remove Flappy Bird.
IMO, do something to force people to take weak cards if you want to balance arena - I don't know how exactly but you are clearly playing with idea of card pools, so maybe try that....pool all the 'bad' cards and force them into peoples decks, with say, 5 picks where you only get sub-par cards. Yes, people complain about getting bad picks right now - but that's because they fear they'll be matched against someone with no bad cards. BUT it's the bad cards that create they interesting play situations that you just don't see in constructed. We want to avoid curvestone, we want to avoid broken win-more cards, we want to avoid cards that are simply busted in arena format (DKs), we want to avoid power creep so that games end so fast decision making is reduced. Bringing all decks down in power level is good for arena, period.

tho it needs to be in your hand, so normally it's still a slightly mid-game card, like prince keleseth. What's the odd of coin prince keleseth shadow step and shadow step
