# Arceus & Dialga & Palkia GX #156/236 — Cosmic Eclipse

## Summary

Arceus & Dialga & Palkia GX was the Cosmic Eclipse trio that anchored the Sun & Moon finale, and the full-art treatment of three Sinnoh heavyweights is Arita's kind of showpiece. It saw real tournament play as a Dragon-type engine, and the Sinnoh pull keeps collectors interested. The sold median sits at $31, up 16% over 30 days on 187 copies traded, with only 9 days of inventory on the board; a PSA 10 brings $230, 7.5 times raw, but a 41% gem rate against $85 of fees makes grading a losing trade.
