Han, Fire main shield, masked man, or play lightning main. Most teams will get swept by the cloud lineup in arena if you cant remove buffs or don't have some sort of barrier advantage. These are pretty much your only options. Focus the lightning main. I ran firemain bee normal garra and masked man for sixpaths. Easy money.

Han, firemain immobile, hanzo, roshi

Yeah if ur having problems with buffs, Han is your man. Though you still have a decent shot at being 1 shot by Ay
