I haven't played epic in a long time, but the best way is the cheesy stun strat. If you want to beat it normally without cheesy strats, then reply to me what the unnerfed version's abilities are and i'll try to help.
Well if the unnerfed version does like 18K+ every turn and summons drones, then i geuss you need to rely on the cheese stun strat. Perhaps there may be another way, but right now, i'm not sure.
