On the physical attacker set:
EVs are designed to maximize Abomasnow's Attack and bulk, while giving it enough Speed to outspeed most Tyranitar and Jellicent.
What is "most Tyranitar and Jellicent"? You're running 173 Speed. What is that outspeeding? You're speed creeping again. We either put speed to outspeeding either minimum or maximum on analyses. Anything else is the choice of the user. Please change that to either 172 HP / 252 Atk / 84 Spe
(preferred, to outspeed min Speed Politoed) or 244 HP / 252 Atk / 12 Spe
(to outspeed min Speed Tyranitar).
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.
