So I figure if I'm playing in Ubers, I should be using my favorite Pokemon at all times. And this is what I've been using lately.
Rayquaza @ Choice Band
Ability:
Not Aerilate Air Lock
Adamant Nature
252 Att / 4 SpDef / 252 Speed
- Outrage
- V-create
- Extreme Speed
- Earthquake / Dragon Claw/ filler
So yeah, Swords Dance and Dragon Dance aren't the only things that work for Rayquaza. I'm loving this Choice Band set. Typically works only as a wallbreaker because of Adamant and the lack of DD, though. Outrage is stupid strong and still usable even with Fairies around, it's just no longer spammable. Anything else not named Heatran dies to V-create, and Extreme Speed is a deceptively powerful move that allows it to function as a revenge killer of sorts. Last move is filler/coverage, but I usually use Earthquake if I feel the need to beat Heatran, or Iron Head if I'm lazy and want to hit Fairies without the worry of stat drops or something.
This set pairs extremely well with BP [Mega] Blaziken, since that speed boost can potentially turn Rayquaza into an "I win" button late-game, and Rayquaza's Water resistance and Ground immunity makes passing any boosts a bit easier. You also wouldn't typically Ice Beam a Blaziken. And as usual, Rayquaza loves his Stealth Rock, since it allows him to OHKO Xerneas on the switch with V-create, assuming Adamant on Rayquaza and no defensive investment for Xerneas.
Rayquaza has undoubtedly fallen a bit in the shift to 6th Gen, since he literally gained nothing in the generation shift other than a weakness to Fairy, but he's still a devastatingly powerful Pokemon. Existence of Fairies doesn't suddenly make him bad, and he's still got a sweet movepool to work with. He requires a bit of support to work at his best, but I'm loving Choice Band Rayquaza at the moment.
