Energy Surge

DefectSkillUncommon
ALL players gain .
Exhaust.

Every living player on your side, you included, gains 2 Energy, then the card exhausts. For you that is a net gain of 1 for the card; each teammate gets the full 2. Upgraded it gives 3 each. It only appears in multiplayer runs, so single-player card pools never offer it.

When to take Energy Surge

Good in co-op when a partner has expensive turns, like an Ironclad with 3 cost Powers or a Regent holding X cost cards. Solo, it is just a weaker Turbo without the Void.
