About this card
Toxic Gas switches off every other Pokémon Power in play, and nothing in the printed text restricts that to the active spot. Fossil is the wrong set to run into it, since nine other powers are printed across these 62 cards and Muk cancels all of them. Arita paints it as a slumped heap of purple sludge with two narrow eyes and shoulders spilling out of the frame on both sides.
