Please don't do this here. The topic 'is tech stronger than magic' is a better place (general discussion board).
OT:
CPU sucks. Any faction can beat any thing if the foe is a CPU and the player is human. I once beat three ultra techs as magic. Of course, I sweated through that game, just because of the sheer numbers that are attacking me. Of course, magic doesn't care so much about high numbers, thanks to static fire. The CPU controlled magic are weak, the human controlled magic are the strongest ever (assuming that the human in particular is me).
