I think it's too early to tell if it's centralizing - spammed on the ladder after a new release does not necessarily equate to centralizing. It's pretty fast but not amazingly, can get up veil relatively easily, but has problems with Stealth Rock (which it shares with Bax) the now-common Knock and a couple pretty notable weaknesses to steel and fire. We'll see if it continues but people are already adapting to Veil spam and it's increasingly becoming a matchup fish archetype rather than the unstoppable one we thought it was. Stacking weaknesses with its buddy Bax doesn't help either- Ghold Gambit and Scizor are kind of eating these teams right now and it just takes one misplay for things to go south for them
Gholdengo has to run air balloon to not get folded by back and scizor isn't really that great beyond these match ups. Calling it "increasingly a match up fish" because people are overprepped for it due to how strong the style is. You're really underselling how strong veil teams are, especially as they're backed by especially strong mons like Manaphy and KommoO.
