As long as Muk ex is your Active Pokémon, ignore all Poké-Powers and Poké-Bodies other than Toxic Gas.

Poison Breath Cost: Grass · 10 damage

The Defending Pokémon is now Poisoned.

10Grading and Population

PSA 10 estimate: Modern ultra/secret rare; PSA 10 populations are moderate and grading is common for higher-value pulls.

Holo scratching and centering are the usual downgrade culprits; graded gem-mint copies trade above raw.

Other graders: CGC and BGS both grade modern ultra-rares; PSA leads on resale liquidity.
