All for One

All for One is a rare Defect attack costing 2 Energy that deals 10 damage and puts ALL 0-cost cards from your Discard Pile into your Hand. This card is the engine that drives the Defect's iconic 0-cost archetype, converting cheap cards into a devastating recursive loop of free plays. With enough 0-cost cards, All for One generates more value than almost any other single card.

All for One is the centerpiece of 0-cost builds, retrieving Claw, Beam Cell, Go for the Eyes, and FTL from discard for repeated plays. Momentum Strike and Streamline naturally reduce to 0 cost, adding to the retrieval pool. Hologram recovers All for One itself from discard, and Scrape draws 4 cards while keeping all 0-cost draws.

For the Defect, All for One defines an entire archetype. Against bosses like Kaiser Crab and Test Subject #C10 where long fights favor scaling, the recursive 0-cost engine generates exponential value. Against aggressive bosses like Vantom, you need enough 0-cost cards in the discard pile to make All for One explosive. Prioritize collecting 0-cost cards once you have All for One, and use Feral to return attacks to hand for even more recursion.
