I see a bigger synergy with a old orc lord more than witn new dwarf lord.
My first thought was this as well until I used my quick cast action to cast
Quick March! battle order and two of these guys ran across the arena, dropped 6 dice on a wounded Infernian Scourger, and at the end of the round I conquered the idol of pestilence and replaced it with a shiny new archer's watchtower.
I personally feel that Anvil Throne can play more aggressively with his abilities than the Bloodwave. Although, in most situations, the Bloodwave can squeeze 1 - 2 more attack dice from his troops.
