Repurpose is such a good card for tech Hero's it allows you to buff up the stat that is needed to keep the villian in check. If the schemes are getting out of control buff THW or if you need to bring them down pump up your ATK, or DEF if you need to stand and take a few hits.
Pinpoint, Tony Stark A.I and Champions Mobile Bunker are to help go through the deck to find and use what cards you need.
Electrostatic Armor, Energy Barrier and Forcefield Generator are there to be repurposed to buff Ironheart stat when needed.
Energy Shields and Enhanced Reflexes are to keep the allies in play for a bit longer, especially Brawn.
Hidden Base and Perserverence allow Ironheart to come back with a tough status to soak some extra attacks.
