I thought we could start a thread where people put the monsters they found most useful/are used by aspect of the game.

Currently, am in episode 3 (beginning),

I find myself using albino lobo for rav, pulse soldier for sen, then for med I was using Cait sith but have switched to spiranthes since it has improved raise.

I haven't done any merging yet- anyone out there know some good ones to start improving to get access to their passive stats?
