Overview
Forbidden Light is a 146-card expansion released in May 2018, representing the climax of the Ultra Beast storyline. Ultra Necrozma GX debuts as the ultimate fusion form with devastating power. The set also introduces Naganadel GX and Beast Ring, a Trainer card that turbocharged Ultra Beast decks. Zygarde GX returns in its Complete forme for the Sun & Moon era.
Best for
- People comfortable with secret rare numbering
- collectors pricing Forbidden Light (2018, 146 cards) as SM GX era cardboard — not as generic “old cards”
- buyers who already know Ultra Necrozma GX Full / Zygarde GX Full Art is the expensive row in Forbidden Light
Skip this path if
- you will not read full secret numbers before paying
- you expect every card in Forbidden Light to carry similar resale (bulk is bulk)
Common mistakes
The expensive mistake on Forbidden Light is skipping surface checks on huge full-art foils. Set code sm6 (2018) is the membership test — character name alone will not save a bad buy. Budget Ultra Necrozma GX Full / Zygarde GX Full Art as priority singles; the other 144 cards are not the same project.
What to check first
Pull up Ultra Necrozma GX Full / Zygarde GX Full Art first — number, finish, and surface — then decide if the ask is real. Parallel check: full collector number (including secret IDs), GX vs full art vs secret. Only after that does the full Forbidden Light checklist tell you what is left.
Most valuable cards
Ultra Necrozma GX Full Art (#127) and rainbow rare (#131) command $15-30 near-mint. Zygarde GX Full Art (#123) appeals to Kalos fans at $10-20. Naganadel GX Full Art (#121) holds $8-15. The secret rare Diancie Prism Star and Lysandre Prism Star add unique collectible value with their prismatic designs.

Tips to finish the set
Forbidden Light is a mid-range set in both size and cost. Beast Ring is a competitively important uncommon card worth keeping multiples of. The Prism Star cards are unique pulls to look for alongside the GX chase cards. Ultra Necrozma GX variants are the primary value targets.
