Strategy & play
How Koga's Grimer 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.
- Inflicts Poison — guaranteed chip damage every turn between turns (no coin flip). It stacks with your attack math to cross KO thresholds the attack alone misses.
- Its main attack (Sludge Toss) needs 2 Energy — a turn-2 swing on manual attachment.
- Needs Grass Energy to attack — your line must supply that color.
- Grass type, weak to Psychic ×2 — a Psychic attacker doing ≥25 effectively one-shots it.
- A single-prize attacker — prize-trade-positive against ex / V decks that give up two at a time.
How to beat Koga's Grimer
- Exploit its Psychic weakness — ≥25 damage one-shots it.
- On the receiving end of a condition? Retreat, switch, or evolve to wipe it — conditions only stick to the Active.

How can I tell if my Koga's Grimer is real?

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.
