XY/ORAS Singles New Team (OU)

[Luckii]

Hey, I've been out of the competitive Pokemon loop for a while now, and I've very recently got back into the fold and started hitting up Showdown again. Since there's been such a big gap, I'm just asking on some tweaking advice for this team I've made for OU 6v6 singles. I've used it and achieved moderate success (12 to 4 win-loss) but there are a number of you on here far more knowledgeable about this than I am so I just cam here for some advice. Anyway, here's the team:

For better or for worse, there's not much to say about this one:

- Consider a Hidden Power type over Dragon Pulse if you find certain threats are causing you problems. I find HP Ice to be the most useful but it'll depend on what you face and need to beat.

- Celebi's fine.

- Keldeo doesn't really need both Scald and Hydro Pump. If Celebi is to be passing Baton Pass boosts to him then a Hidden Power would likely help more.

- Skarmory's had the same set for about 10 years with very little variation, so it's fine.

- Unless you're planning on targeting very specific threats with them, the elemental punches really don't do much for Rhyperior since Ground/Rock covers a lot of the stuff that you'd need to hit with them. Moves with higher base power like Hammer Arm and Megahorn will probably be more useful. Also consider Choice Band or Assault Vest as possible items to use since you're running four attacks anyway.

- Ah, FR/LG meta, good times.
