  • Required for any complete Muk master set across eras.
  • Collectors of the Gym Challenge set need this card to finish it.

08Competitive Playability

Tier: None

Stage 1 Muk with 80 HP; top attack around 40 damage. Functions as an evolution-chain piece rather than a tournament attacker.

09Card Moves and Abilities

Ability: Energy Drain

If an opponent's attack does damage to Koga's Muk (even if Koga's Muk is Knocked Out), flip a coin. If heads and if it has any, choose 1 Energy card attached to the attacking Pokémon and discard it. This power can't be used if Koga's Muk is already Asleep, Confused, or Paralyzed when your opponent attacks.

10Grading and Population

PSA 10 estimate: WotC-era Muk PSA 10 populations vary; small numbers across most sets.

Graded copies command notable premiums over raw, especially for 1st Edition prints.

Other graders: BGS and CGC also grade vintage Pokemon; PSA dominates secondary-market liquidity.
