Although Alolan Muk probably still prefers Po Town to set up Acerola plays.I wouldn't say that. It makes inflicting status a lot more useful because it shuts down one of the ways they can cure it. I could see this being fun with Alola Dugtrio to increase their retreat cost and Field Blower to shove away any float stones that are hanging around.
Muk GX is going to love this. So will pokemon that inflict Confusion, Poison decks that abuse Seviper, Pokemon like Mega Ampharos and Mega Venusaur that can constantly Paralyze the target, decks that use Porygon-Z or Espeon EX to devolve and kill basic pokemon between turns.. It is a situational card, but far from useless.
