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.

eBay sold listings by grade, last 90 days.
Data through May 3, 2026.
Based on a raw cost of $12.18 (Near Mint) and the median of recent eBay sales at each grade. Each figure is what you'd net after grading and selling — the grading fee, a $15.00 shipping estimate, and a 12.9% sale fee are already subtracted. It doesn't predict the grade your card will get; it shows what each outcome is worth so you can decide.
