Hologram

Hologram is a common Defect skill that costs 1 Energy, gains 3 Block, and lets you put a card from your Discard Pile back into your hand before Exhausting itself. This retrieval effect is incredibly powerful, essentially letting you replay your best card each time Hologram is drawn. The small Block bonus is a welcome extra on an already excellent utility card.

Hologram pairs brilliantly with Seek to first tutor a card from your draw pile, then later recover it from discard with Hologram. It also works well with Overclock, letting you retrieve the Overclock after its Burn has been dealt with, and with Fission, since recovering Fission from discard allows repeated Orb-to-resource conversion.

As a Defect player, Hologram is one of the strongest common picks in the game. Against bosses like Knowledge Demon where one key card can swing the fight, Hologram effectively doubles your access to it. In All for One builds, Hologram's Exhaust nature means it clears itself from your deck after use, thinning toward your 0-cost engine. Pick this card in almost every Defect run.
