What cards did he pick to go with that?
I'm very confused as to the purpose of this one. About the only thing I can say is that it looks fairly versatile.
Did you happen to be playing undead?
Yes, I was playing the Zombie Dragon army. I was confused by the purpose of his selection too, I think he had the idea to move everything in a sort of phalanx, with the copter and pistoliers darting around the flanks. He had Rally, Grim Resolve, Myrmidia's Blessing, Shield Wall, Speed of Asuryan, and Entrap.
He used Rally and Franz to get quite a lot of shots with the Flame cannon, but rolled horrendously and consequently did next to nothing. Grim Resolve, however, proved very effective against my army. Ultimately I won by 10 points by killing his heroes (he had the deployment zone objective).
