2:12 My first hero discovered a lot of allies: 1 Giant Worm, 4 Devils & 4 Dragons. I also got a quick 2nd hero with 1 Dragon on turn 4 & 2 Demons with that guy shortly after.
3:35 big whoopsie... skipping turn 3
Later on I think I did a decent job stopping armies coming into my territory. A few got through anyways, but I could contain the attack in a few turns usually.
