Double Colorless Energy

The 2017 Guardians Rising Double Colorless Energy is a secret rare Energy card, illustrated by 5ban Graphics. Raw near-mint copies trade around $17.57, while a PSA 10 is modelled near $62.57 and a PSA 9 near $35.57. In its original set it is a chase card — roughly a 1-in-2,000 booster pull (modelled, not official). Double Colorless Energy has 12 other printings in the catalogue.
