Evilkin and Dejan had been testing Spiketail Hatchling vs Flying Men and agreed that the hatchling would be better.
The third crucible was great, and I would have liked a third Old Man, especially against fish. I never had a hard time with the 3cc (maybe I'm just lucky

). If I resolved an Old Man first game I won. Against 4cc it gave me extra turns to attack, because he needed to get rid of the old man before he could morph in an angel. By the time he was able to, he was low enough that I could finish him off. Against workshop, stealing welders was key. Against fish, thanks for the lavamancer.
The curiosities weren't as useful as I would have liked. Most of the time the opponent was able to deal with the creature before I got to abuse it. Swords, Lavamancer, flying blockers (including pentavite tokens), Fire, etc. all hindered my curious creatures. Still, when it did work out for me, it was great.
