I believe Alchemy on arena has a power problem the heist deck mechanics are too strong first of the triumphant getaway not being legendary and being opponent loses 2 life you gain 2 life and having flash is too much this is an issue that should of come up in play testing. Second the lootmongers ability really should be once per turn. These should be simple changes that should be implemented as soon as possible this one deck type is a plague on the format at its current power level.
