Strategy & play
How Ultra Necrozma-GX plays — derived from its stats and the rules of the game, not an opinion.
- A Basic — hits the board turn 1 with no evolution tax.
- Its main attack (Photon Geyser) needs 2 Energy — a turn-2 swing on manual attachment.
- Needs Psychic / Metal Energy to attack — note its own type is Dragon, so build for the attack cost, not the type.
- Dragon type, weak to Fairy ×2 — a Fairy attacker doing ≥95 effectively one-shots it.
- A two-prize Pokémon — each KO gives the opponent 2 Prizes, so a single bad trade can lose the race. Back it with single-prize attackers.
How to beat Ultra Necrozma-GX
- Exploit its Fairy weakness — ≥95 damage one-shots it.
- It gives up 2 Prizes — out-trade it with single-prize attackers.

Frequently asked
How can I tell if my Ultra Necrozma-GX is real?
Ultra Necrozma-GX is not on our list of commonly-counterfeited cards, but counterfeits exist across every set. Check the back-light test (real cards have a black inner layer that blocks light; counterfeits glow through), the rosette dot pattern on the back under magnification, font weight and kerning on the card name, and the holofoil pattern if applicable. For high-value copies we recommend submitting to a professional grader (PSA, BGS, CGC) for tamper-evident authentication.
