Strategy & play

How Omastar plays — derived from its stats and the rules of the game, not an opinion.

  • Its main attack (Send Back) needs 2 Energy — a turn-2 swing on manual attachment.
  • Needs Water Energy to attack — your line must supply that color.
  • Water 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.
  • A Stage 2 — without Rare Candy you lose ~2 turns setting it up, and it’s gust-bait before it’s online (you must draw Omanyte first).

How to beat Omastar

  • Exploit its Grass weakness — ≥55 damage one-shots it.
  • Gust it before the evolution is set up.

Frequently asked

How can I tell if my Omastar is real?

Omastar 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.
