Madame X gets a Yveltal Crest that buffs the power of Razor Wind and makes it summon a Floatzel ally lol

Imagine you enter a wild battle with one Floatzel and end up running down the valley, being chased by an overwhelming sea of Buizels that keeps growing exponentially.

Doesn't Buizel, the weasel pokemon, learn Razor Wind? That means you could infinitely generate weasels. Buizel uses Razor Wind, summoning Weasels (Buizels?) which also apparently can use Razor Wind, summoning further Weasels.
