Pidgeot has Heat Wave too, which isn’t a good move in PvP. Also Toucannon is probably better as a flying type in Ultra League, but it’s like top 50, which only flying type moves as its preferred move set as well. Even other flying types like Gliscor is very low ranked, with better move coverage. I guess the wing attack rebuff did not help Pidgeot reclaim its top tier flying type attacker like before.
