Nice typical Ho-ohfense team. I can see a CM RestTalk Kyogre being a nuisance to this team. Although it's not going to readily sweep your team, it can repeatedly come in and get rid of the Sun, severely hampering your progress. Palkia is not going to be able to stop it easily either, since it can Calm Mind up and Thunder is not going to 2HKO. I suggest replacing Deoxys-A with Latias and moving Forretress or Groudon to lead position.
Latias @ Soul Dew
EVs: 112 HP/204 SpA/192 Spe
Can CM up along with CM-Ogre and kill it. Thunder is better even with the Sun on your team since Grass Knot makes Latias complete Steel bait, and Kyogre is common enough for you to run Thunder anyway.
Whatevs sig. QC member for OU and Ubers, VM me for a look at your analysis. Just make sure it's good.
Also, if you want me to rate your team (OU/DW OU/Ubers), give me a VM. If I don't rate it, it's either 1) it's so shit it's too much trouble, 2) I'm busy, or 3) the team is fantastic and I have nothing I can suggest to you. You should be able to recognise which one.
