Strategy & play

How Koga's Muk plays — derived from its stats and the rules of the game, not an opinion.

  • Its main attack (Sludge Whirlpool) needs 3 Energy — a turn-3 swing on manual attachment — you’ll want Energy acceleration to power it up on time.
  • Needs Grass Energy to attack — your line must supply that color.
  • Grass type, weak to Psychic ×2 — a Psychic attacker doing ≥40 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.
  • A Stage 1 — one step up from Koga's Grimer; doesn’t help your opening hand, but quick to set up.

How to beat Koga's Muk

  • Exploit its Psychic weakness — ≥40 damage one-shots it.
  • Gust it before the evolution is set up.
  • Trap it Active — 3 retreat means it can’t escape without help.

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

For high-value copies we recommend submitting to a professional grader (PSA, BGS, CGC) for tamper-evident authentication.
