You picked all the new yugioh cards. Hate those...

Looks like a good team, and you know it is. Though, you might have trouble with Kyogre, as you said Rayqueza is your only good switch in. And if the opponent is predicting well that day, it's good by Rayquaza.

Then it 2HKO's all your Pokemon with Waterspout, that's without rain. If it's scarfed, Mewtwo will have trouble exploding on it. I'd try Thunder somewhere on your team, maybe over Taunt on Mewtwo?

I don't really play Ubers, so if I'm missing something about your team sorry.
