I guess Choice Scarf Abomasnow has that one little niche of being able to outspeed all the Chlorophyll sweepers (apart from Lilligant) without having to spend two turns changing the weather, and then switching to your revenge killer, and THEN attacking, in which time if your opponent has good prediction, they might have killed two Pokemon already. Abomasnow could kind of switch in on a revenge and then Blizzard the Venusaur or Sawsbuck o Shiftry or Jumpluff to high heaven without needing to go through all that other crap. Still, I guess that doesn't require a whole set, but if Scarf is to go into OO, it needs this bit of information (killing Chlorophyll abusers as well as maybe Stoutland and Sandslash) included.
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.
