# Boost Energy #145/147 — Aquapolis

## Summary

Boost Energy was a one-shot Special Energy that let an evolved attacker hit hard a turn early at the cost of retreating, a trade e-series players weighed carefully. As an uncommon from a late Wizards set it was a tool, not a chase, and Yoshikawa's name adds a small collector footnote. The modelled guide sits at $7.17, up 5% over 30 days on 5 copies traded, with 273 days of inventory on the board; PSA does not split this card’s population by finish, so no gem rate can be read for it, with original packs long past any pull-rate math.
