Fire main that runs any mystery but the shield becomes far stronger.... The usually ignored ignition mystery actually does a lot of damage because of the ignition (and no ooldown while your clone is on the field). The immobile + inprision mystery can make a water or wind main skip a round, and take 40% of their hp in recoil when they use any mystery next round. The giant fireball mystery is pretty much a hard counter to any clone based team. If you do run the shield, then yes, he is bad in most teams in zenith.
