Charge Battery

Charge Battery is a common Defect skill costing 1 Energy that gains 7 Block and grants 1 Energy next turn. This forward-looking design provides solid immediate defense while fueling a more powerful subsequent turn. The delayed Energy gain effectively makes Charge Battery a 0-net-cost card over two turns while providing substantial Block.

Charge Battery pairs well with Double Energy, as the extra Energy next turn gets doubled for massive resource generation. Glacier provides complementary Frost-based defense, and Skim ensures you have cards to spend the bonus Energy on. Boot Sequence offers similar frontloaded defense at 0 cost with its Innate keyword.

For the Defect, Charge Battery is a solid early-game defensive pick that smooths out Energy-hungry turns. Against bosses like Lagavulin Matriarch where you need to set up before they power up, banking Energy with Charge Battery lets you deploy key Powers like Echo Form or Creative AI a turn earlier. It is reliable in any Defect deck and particularly useful when running expensive cards.
