Can someone tell me why Aurora Veil is more broken than Reflect/Light Screen? I honestly don't get the NU ban.
You can Defog it, Brick Break it or Psychic Fangs it(hi sharpedo)
Also Nidoqueen is crazy, already making a great impact in RU. Love it
To elaborate a bit, it is both moves in one, and the Pokemon that use it, A-Slash and Cryogonal, the latter of which can also set up Reflect/Screen on top of A-Veil, are Ice types and most every Defog user is weak to Ice types so you can't defog on those Pokemon, and when they switch out to a set up Pokemon any Defog user will be pressured against practically every set up Pokmeon that A-Veil teams run.
Psychic Fangs is only used on Bruxish and Sharpedo which is makes use already super small, both are also pretty frail, and the A-Veil teams run Pangoro in the RU environment which will prevent Fangs from breaking A-Veil due to immunity. Seeing as both are RU by usage that leaves the only Psychic Fang user in NU being Stoutland who probably doesn't have much general usage.
Since Defog users are pressured easily by the strategy and P.Fang users very few in numbers and even then Shark won't have it on every set or most times in general, that would leave Brick Break, and that's a very bad move to have to be running just to counter a strategy. Most Pokemon that can run BB would rather have a stronger fighting move because they need it for damage against the rest of the metas (both in RU and NU). Difference between moves like Defog/Spin are being used for supporting a team, whereas BB is supposed to be an offensive move that basically removes Screens with extra damage if they are set up. Optimally there's no draw backs to running Defog or Spin on Pokemon who generally learn it as their movepools allow it, BB while being learned by many Pokemon can never find a place to be ran over Superpower or Close Combat due to needing to get kill shots. If you have to run a bad offensive move to help counter a strategy that's pretty bad.
It would just be better running a different weather setter to counter the Hail than running a Brick Break user tbh, but then that just would make a tier of I guess weather wars and something not everyone will want to run on every team just to counteract a weather + double screen strat.
Edit: There are also replays showing how good the strategy in simple form but I don't have any showing potency in RU, and if you want the NU replays, Meeps posted some of his in the
policy review discussion of A-Veil in NU right there.
