"Go Thesaur- oh, it's not part-Fairy yet. Go Magneto!"
"I'll be glad to pulverize this small icy fox."
Magneto the Metagross @ Amulet Coin
Meteor Mash~Iron Head~Meteor Mash
IF Meteor Mash is disabled when you would use it, THEN replace it with Iron Head
IF Vulpix has Double Team clones, THEN use Earthquake and push back actions
This status effect causes a Pokemon to become disoriented for a while. When a Pokemon becomes confused, its confusion counter will start at either 2, 3 or 4, with a 1/3 chance of each. As with sleep and freeze, the Pokemon's confusion counter is checked at the start of its turn and the Pokemon snaps out of confusion if its confusion counter is 0. If it is not 0, however, then there is a 1/3 chance that the Pokemon will not perform its intended action, but will instead hit itself in confusion.
I noticed you rolled for a 1/2 chance, so I just wanted to point this out.
"Well, since YAS basically cheated and brought his Yveltal, I don't feel I can really risk Magneto in this matchup, what with being confused and at a type disadvantage and all..."
"Uh-oh..."
"Go Thesaurus!"
"You want ME to take down a LEGENDARY BIRD OF THE NIGHT with a type disadvantage?!?"
"Well, not with that attitude..."

IF Yveltal is in the evasive stage of a D/E when you would act AND not suspended AND not in a combo AND Sludge Bomb is disabled, THEN use Sludge + Sludge and push back actions.
