Mewtwo-GX

Mewtwo-GX sits at #31 in Hidden Fates, released in August 2019. Hidden Fates is part of the modern English Pokémon TCG era and uses the standard contemporary card frame and rarity tiers. Illustration by aky CG Works.

Hidden Fates shipped in Holofoil and Reverse Holo, plus a special Shiny Vault subset (numbered SV1 through SV94) that runs alongside the standard 69-card set. Shiny Vault cards use alternate-color shiny treatments and pull at lower rates than the standard holos.

For graded buyers, modern cards have cleaner cardstock than the Wizards-era prints, so the grading bar is higher. A PSA 10 on a modern holo or alt-art requires close to flawless centering and pristine surface. PSA 9 populations are large; PSA 10 populations on the marquee chases (Special Illustration Rares, alt arts) are the cards that actually move price. Submission math favors clear PSA 10 candidates and stays away from PSA 8 or 9 outcomes.

If you are buying this card, the order of operations is rarity tier first, then condition. Confirm whether you are looking at the standard holo, an alt art / Special Illustration variant, or a Hyper Rare; the price spread between tiers is often 10x or more. For raw purchases on chase-tier modern cards, insist on photo or video showing the holo surface and edges. Modern cardstock is stiffer than Wizards-era stock but the high pull rates mean PSA 10 supply is large; price your buy against PSA 10 population reports.
