For aesthetic and programming purposes, fix the set into this:
Correction attempt fail, AG. It's SpA, not SAtk.
God get your game together mate.
So yeah, Shurtugal, please change it to 4 HP / 252 SpA / 252 Spe
Anyway, onto the set, and I'm sorry if I'm going to play the Devil's Advocate here. On one hand, I'm not a fan of "Expert Belt bluff" sets that focus mostly on the surprise getting analyses, because 1) by having the set on-site, you just killed the surprise, 2) surprise sets need to have uses outside of the surprise itself, and 3) is Expert Belt really the best item? For (3), I personally don't think Keldeo's super effective coverage is really that great, since what you'll mostly be doing is just spamming Hydro Pump. If that's the case, Mystic Water / Splash Plate might be the better option for the item, unless Expert Belt gives you some important KOes (which I'd like to see damage calcs for!)
On the other hand, this set plays quite differently from the rest of Keldeo's sets and is good enough as a stand alone set to warrant an analysis on its own. I'm not rejecting this in any way, but I'd like you to keep my concerns of "Expert Belt bluff" sets in mind when you're writing this set and others.
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.
