Team is obviously really good, so not much to say.
Echoing what Stone_Cold mentioned, I don't like running Spikes on HO teams now that Deoxys-S is gone. A team like this needs momentum to thrive, and Stealth Rock is really the only thing that is needed on a team like this. I've been running a similar team and I've found that Lead Azelf works much better than Deoxys. An EV spread of 252 HP/ 252 SPE 4 SPA with a Timid nature and the moves Stealth Rock, U-turn, Taunt, and Fire Blast. I agree with ShakeItUp's suggestion on running a Expert Belt Rotom-W, as Tentacruel can prove problematic. Personally, I like to run a ChestoRest Rotom-W as you still get to bluff a Choice Scarf and hit Tentacruel, but you also get some added longevity.
