Subroutine

Subroutine is an uncommon Defect Power costing 1 Energy that grants 1 Energy whenever you play a Power card. This Energy refund mechanic makes subsequent Powers effectively cost 1 less, enabling Power-chaining turns where you deploy multiple Powers without running out of resources.

Subroutine pairs beautifully with Creative AI, which generates free Powers each turn that also refund Energy via Subroutine. Storm channels Lightning for each Power played, creating a dual-benefit engine. Amplify doubles the next Power for maximum impact, and White Noise generates a random free Power that triggers Subroutine's Energy gain.

For the Defect, Subroutine enables Power-spam strategies that would otherwise be too Energy-hungry. Against bosses like Kaiser Crab and Test Subject #C10 where long fights favor accumulation, each Power played fuels the next. Against Doormaker, chaining Powers in a single turn with Subroutine's Energy refunds can establish an overwhelming board state. Pick Subroutine when your deck features 5+ Powers.
