The Pokemon Company headlined the set with Ultra Necrozma-GX, Lucario-GX, Greninja-GX, Zygarde-GX, Yveltal-GX and Arceus Prism Star.

Why do rainbow secrets lead?
TheGamer reports Lucario-GX #135/131 at about $51.63 and Greninja-GX #133/131 at about $42 to $47 lead raw Forbidden Light values. See TheGamer's Forbidden Light value rankings for the full raw-value order. Greninja-GX #133/131 sold for $507 in PSA 10 on Aug.
24, 2026, per PriceCharting and PokeInvest tracking in PriceCharting's Greninja-GX sales history. It now tracks near $726 versus about $75 raw, or roughly a 7-9x multiplier. Lucario-GX #135/131 tracks at $605 in PSA 10 versus about $70 raw, per PokeInvest current tracking in PokeInvest's Lucario-GX tracking. PokeInvest puts PSA population near 287, leaving about $535 gross spread before grading fees.
Does the set mascot clear grading costs?
Ultra Necrozma-GX Full Art #127/131 sold for $175 to $209 in PSA 10 in June 2026. Sports Card Investor reported those June 27, 2026 sales against about $20 to $23 raw.
The set mascot therefore clears grading costs in gem condition. Off-center or worn copies do not carry the same math.
Can a cheap Prism Star justify grading?
Arceus Prism Star #96/131 guides at $154.50 in PSA 10 and sold for $220 on Mar. 12, 2026.
PriceCharting recorded that sale, with raw copies around $7 to $15, in PriceCharting's Arceus sales history. Clean Prism Stars can therefore justify grading despite low raw prices. Centering, corners and surface decide whether this card pays.
What keeps most holos from PSA 10?
PSA reserves GEM MT 10 for virtually perfect cards on its 10-point scale, according to PSA. Off-centered or edge-worn Forbidden Light holos commonly return PSA 9 and lose most premium. With PSA-type fees around $15 to $50 per card plus shipping, prescreening matters.
The PokeInvest PSA calculator note gives that fee range and favors $150-plus PSA 10 comps. Prioritize rainbow secrets and clean Prism Stars with strong PSA 10 comps. Submit only centered, sharp copies that can survive the GEM MT bar.
- Check centering front and back under good light.
- Check corners, edges and surface for whitening or scratches.
- Compare recent PSA 10 sales before paying fees.
