I found a cool glitch, you can resurect enemies with the mages last spell even if you have 8 units out you can keep resurecting enemies, that was a big help on "oh snap its Greg" I had like 17 units out.
I felt like I was cheathing in new game plus :/
I had the Kong ant as a swordmaster equiped with the dragons jaw.
Demon Lord as a warrior with the hell weapon
Angel as the horse class with the spear that freezes stuff and
a cyborg as a tanker with the freeze ray you get off P-Bot
