^And Deoxys-D. We can't forget about that.
Any dark types with respectable speed and attack destroys em. Or bug types.
See: Weavile, Volcarona
For the love of Pete, people should just drop this argument already!
Oh my gosh, I can list two counters/checks. That means it is clearly not viable right? I mean, it's not like Scizor is beaten by anything fire type, right? Oh, and choice scarf primape can beat Darkrai, so it should be ubers!
Let's be honest, Dark/Bug types are pretty rare in OU. Volcarona and Scizor are just about the only offensive ones you'll see. And Dark? There is the Weavile you suggested, but not only is it uncommon, it isn't even considered OU. And anyway, let's say you swap it in on a Uxie as it uses Reflect. Great, now all of your super effective attacks do normal damage, and with those defenses, it can probably get up a light screen and then finish it with memento to cripple you and force a swap out for your set up sweeper. Or if I'm wrong and it can't, reflect should be enough since most priority moves, choice scarfers, and OU pokemon in general are physical.
If you want to say a pokemon is bad, give a real reason, not just "oh, this pokemon can beat it so it's pointless".
Latios would be better yes but the reason why no one every uses uxie is because alot of people think that uxie is just well a useless pokemon but really uxie is just a pokemon who can't learn the best moves and dosen't have the best power
No, it's just that their isn't really a good reason to use it 99.9% of the time. It's viable, but it should only be used if you just really like Uxie.
