# δ Rainbow Energy #88/101 — Dragon Frontiers

## Summary

δ Rainbow Energy was the glue of Delta Species decks, letting a single attachment cover whatever types a δ Pokémon needed, so it saw steady tournament play in its format. As a mid-tier Uncommon in a set with a small player base, it stayed cheap to pull while remaining a real staple. The modelled guide sits at $1.11 with 3 copies traded in 30 days; PSA does not split this card’s population by finish, so no gem rate can be read for it.
