A strong Power that refunds 1 Energy every time you play another Power. Upgraded to cost 0, the card pays for itself on deployment.

In Power-heavy builds it dramatically improves Energy economy. Decks packed with Storm, Creative AI, Machine Learning, Coolant, and other Powers see their Energy crunch vanish thanks to Subroutine. Upgrading to 0 makes its own cost disappear, turning every subsequent Power into a discounted play. A mandatory piece for Power-centric decks.

• Deploy early in Power-heavy decks to stack the refunds for as many turns as possible
• Prioritize the upgrade to cost 0
• With Storm, each Power both Channels Lightning and refunds 1 Energy
