Heatsinks
Heatsinks is an uncommon Defect power that draws 1 card whenever you play a Power for 1 Energy. In Power-heavy Defect builds where you're playing multiple powers per fight, each one draws an additional card, sustaining hand size and finding more key cards. The effect is passive and permanent once Heatsinks is on the board.
Heatsinks provides exponential value as more Powers are played in a single fight. Playing Defragment, Capacitor, and Electrodynamics each draw 1 card, netting 3 draws beyond normal card advantage. In a deck that regularly plays 3-5 powers per fight, Heatsinks effectively adds 3-5 free card draws — keeping your hand full throughout setup. Upgraded, each Power played draws 2 cards instead of 1, dramatically improving draw density in Power-dense builds.
