SM10A PSA 10 Guide
Set History & Release Context
GG End (強化拡張パック ジージーエンド, sm10a) released in Japan on April 5, 2019 as the Enhanced Expansion Pack companion to Double Blaze (sm10). The set sits late in the Sun & Moon Tag Team GX era and was Japan-exclusive — there is no direct English counterpart, with cards instead localized across Team Up through Unbroken Bonds equivalents.
The 69-card set focused on expanding the Tag Team GX roster introduced earlier in the block, while reprinting and updating supporters and trainer cards relevant to the post-rotation 2019 competitive format. The set name 'GG End' is a fan transliteration of the katakana title (Bulbapedia accessed 2026-05-09).

Top Chase Cards Explained
The marquee chase cards in sm10a are the Tag Team GX duos — Garchomp & Giratina-GX (with HR rainbow and SR full art variants) and Raichu & Alolan Raichu-GX. Single-Pokemon GX hits include Mawile-GX and Heatran-GX, each printed in Ultra Rare and Hyper Rare rainbow treatments.
For PSA 10 collectors the rainbow rare (HR) Garchomp & Giratina-GX and Raichu & Alolan Raichu-GX are the standout pulls due to crossover demand from the matching English Unbroken Bonds prints, while Heatran-GX SR commands a niche following among single-Pokemon GX collectors.
Investment Analysis
sm10a sits in the maturing Tag Team GX collector segment: not vintage, but supply was capped to a Japan-only run and the era is now closed. The investment thesis rests on Tag Team GX nostalgia (the mechanic was retired with Sword & Shield), Japan-exclusive scarcity vs. English equivalents, and the strong artwork continuity with Unbroken Bonds. Pack-fresh Japanese boxes are sealed-market favourites for graders targeting PSA 10 rainbow rares.
