Team Up arrived in early 2019 as a collaborative set celebrating the bond between trainers and Pokemon. Released during the Sun & Moon era, it marked a significant moment by introducing the Tag Team mechanic, fundamentally reshaping competitive and casual play alike. The set's dual-focused approach generated considerable collector interest and remains a touchstone for players who experienced that period of the game's evolution. Darkness Energy is a classic type energy card from the set, rendered in the holographic treatment that defines Team Up's visual appeal. Collectors appreciate energy cards for their elegant simplicity and essential role in any player's collection—they're the foundation upon which every deck is built. Holographic energies from this era have become increasingly sought after as Team Up's legacy has grown among both nostalgic players and newer collectors discovering the set's charm.
