Here, of course, the generator made the call, which isn't particularly kind to Necro. I had one Barbarian secondary hero, along with plenty of gold, resources, a large respawn, and a bunch of Gremin huts. My opponent, on the other hand, had lots of blockers, and the paths to secondary hero recruitment were guarded by ranged stacks, even though there was a direct passage to the treasure zone.
Thanks for the game.
