The idea is to use Defiance with Rapier Fanatic for a 6-cost 20/7 Charge, which will neither be sacrificed at the end of the turn or have the weakness of having 1 Health.
Agent Coyle, Mechborn
1 Martyr Golem
3 Defiant Engineers
3 Support Drones
3 Treasure Hunter 3000s
3 Flame Dawn Commandos
3 Fleeting Footmen
3 Paladins of the Flame Dawn
3 Rapier Fanatics
3 Controlled Temporal Anomalies
I considered adding Tailored Knights, as well as Defiant Engineers to make the most out of these and the Treasure Hunters, but didn't in the end.
This is actually my first attempt at a 2GI/1FD deck, since I usually play 2FD/1GI if these purities are mixed, so feedback is appreciated.
EDIT: Removed Tinkerer and Bromich from Command, replaced by Splitter Robot and Tailored Knight. Removed FD Hounds and Splitter Robots from deck, replaced by 3 Defiant Engineers and 3 Controlled Temporal Anomalies.
