Lore

Why it matters

This Secret Rare Unit Energy card from the Ultra Prism set is highly regarded for its utility, as it provides three different energy types—Grass, Fire, and Water—in a single card. Its inclusion as a "Rainbow" or gold-etched secret variant makes it a functional yet aesthetically distinct centerpiece for collectors focused on the Sun & Moon era.

Provenance

Where it came from

The Unit Energy GrassFireWater card was introduced in the Sun & Moon—Ultra Prism expansion, released by The Pokémon Company in early 2018. As a specialized energy card, it was designed to support multi-type deck compositions by providing different energy requirements in a single attachment, a mechanic intended to add strategic depth to the competitive trading card game landscape during the Sun & Moon era.

This specific iteration, numbered 170/156, is a secret-rare version of the card, distinguished by its gold foil finish and textured etching. The illustration follows the high-production aesthetic standards of the set, emphasizing a metallic, premium look that appealed to collectors of the Ultra Prism series. Upon release, it was noted primarily for its utility in niche deck archetypes and its status as a sought-after aesthetic upgrade for competitive players looking to maximize the visual cohesion of their decks.
