Strategy & play
How Onix 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.
- Needs Fighting Energy to attack — your line must supply that color.
- Fighting type, weak to Grass ×2 — a Grass attacker doing ≥45 effectively one-shots it.
- A single-prize attacker — prize-trade-positive against ex / V decks that give up two at a time.
- Retreat cost 3 — gets stranded Active if gusted; run Switch / Escape Rope or a Float Stone-style Tool.
How to beat Onix
- Exploit its Grass weakness — ≥45 damage one-shots it.
- Trap it Active — 3 retreat means it can’t escape without help.

Frequently asked
How can I tell if my Onix is real?
Onix 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.
