Hero PowerSummon three 1/1 Microbots.Swaps_each_turn.
I think micro squad is on the same tier list as Zap Cannon in terms of Boom Hero Powers, but I prefer Micro Squad a little bit better. It allows you to divvy up your damage how you choose, and the small mech bodies are perfect magnetic targets.
Something to ponder. This guys will be 1/1s with Rush.
