That's even better, thank you. And yes, royal griffins would probably be the most effective. They have a reasonable amount of health so I'm less likely to lose them when trying to do no-loss battles, and their summons are immensely useful for controlling losses as well.
I have a bunch of snake eggs and griffin eggs, which I assume with produce crap units (the weakest of the creature series), so it's nice to finally have a use for them.
