Even then, it's only ever really relevant when Fairy types aren't dominating the tier. If Xerneas is everywhere, Yveltal disappears from usage stats. Ho-oh fulfills a lot of the same roles as Yveltal while having Regenerator, though Yveltal is still more splashable since it has U-turn and Knock Off.
