High level arenas eat up with cheats

Been playing on bluestacks tonight, level 23, rank 7228, highest 8203. Anyways, have fought one guy that could use Sci fi Kenny over and over. Hidden energy staffs and one guy that could spawn a field full of the first toon he threw. Anyone else seeing this at these levels? All these guys where level 25, I don't even have a level 7 card. lol
