Beginning Super Combatants

[Foodstamp]

Gorgon is insanely overpriced (in vanilla she is very affordable for Sauromatia for an easy E9N4 bless, which means she has to be ridiculously overpriced in CBM; the sad thing is that for the nations she would thematically fit for never ever get her for competetive play) in CBM, but in singleplay a E4N4A2 Dom9 will work wonders. Script Cast Airshield, Attack Rear and watch her go medieval. If you can on first turn craft a shield (aka access to nature or earth gems to craft a shield on turn 1), then do that to make her practically impossible to hurt by indies).

Like Jarkko says, the Gorgon is tough to beat.

Another really good one is the Risen Oracle for Agartha. In single player you can get away with a 4 earth/ 4 nature/ 4 death/ 1 astral and he is a beast right out of the box on turn 1. After a little research, you have an assortment of great SC buffs, the ability to forge very good SC gear, he has a boatload of HP, and he is immortal. WEEE!
