Attacker

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.
  • Its main attack (Tail Smash) needs 3 Energy — a turn-3 swing on manual attachment — you’ll want Energy acceleration to power it up on time.
  • Attacks on any Energy (Colorless cost) — splashable into any deck regardless of type.
  • Fighting type, weak to Grass ×2 — a Grass attacker doing ≥55 effectively one-shots it.
  • A single-prize attacker — prize-trade-positive against ex / V decks that give up two at a time.
  • Retreat cost 4 — gets stranded Active if gusted; run Switch / Escape Rope or a Float Stone-style Tool.

How to beat Onix

  • Exploit its Grass weakness — ≥55 damage one-shots it.
  • Trap it Active — 4 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.
