Second and third runs of insane have been much easier with achilles. If you don't have a werewolf or ss, as I suggested earlier, a strong achilles helper replacing your royal fencer will give you a pretty much guaranteed run here (provided you have that naga and your two shooters). You could probably replace hp beasts with full healers (mermaid princess, phoenix, dryad, unicorn, homonculus), though those are really just as rare and having one and not the other is really just situational. This is still much tougher than water apoc, but you at least have a few options. I really like the point made earlier that fire cards gives you control, since they only attack when you use their skills. Potentially useful.
Also, where can I get an enchilada card?
