Here's a custom Mastermind Magus and Technarchy Henchman. This is something I had worked up a while ago but didn't make cards of. It uses the keyword Infect. When you Infect you gain a wound and put it on top of your deck.
Magus's Master Strike makes you reveal a Tech hero or Infect. He gets stronger the more wounds you have as you get infected by the techno-organic virus. He leads the Technarchy Henchman whose only goal is to Infect you. Challenge mode: Play with the Legacy Virus and no Tech heroes.
I'm still working on testing the next Mastermind in the Pro-Reg set.
