# Energy Switch #21/30 — HS trainer Kit (Gyarados)

## Summary

Energy Switch is a pure utility Trainer, the sort of effect players reached for to shuffle Energy between Pokémon, never a showpiece. Packaged in a trainer kit as a starter deck component rather than a booster pull, it carries no chase appeal, and Kawahara's name on it is a small bonus for completists. At a $4.26 modelled guide, with 2 copies traded in 30 days, this printing is almost entirely collector premium, since the same card plays for $0.20 out of Mega Evolution; no PSA population is on file.
