After a few battles, I've come to a conclusion that Technician Weavile would be an absolute monster. Here's one of the better battles I had. I was using an old hail team that I turned into a standard team by replacing Specs Kyurem with Specs Latios and Abomasnow with Weavile itself. The team functioned like a usual T-Tar + Keldeo core but instead of T-Tar I used Weavile to better handle Jellicent and for revenge killing the Lati Twins.

I was using this set:
Weavile @ Life Orb
Trait: Technician
EVs: 252 Atk / 252 Spd / 4 HP
Jolly Nature
IVs: 0 Atk
- Ice Shard
- Pursuit
- Bite /
(Testing Beat Up)
- Low Kick
If Technician Weavile existed, this would probably be the best anti-metagame set it could run. Because Ice Shard is so damn powerful when boosted by Technician, there's no reason to ever run both Ice Shard and Ice Punch on the same set, allowing you to fit both Pursuit and another Dark-STAB for different situations. Weavile has access to two 60 base Dark-type moves; Bite or Faint Attack. Although Bite has a chance to flinch, I chose Faint Attack just for the lols, but in most cases Bite would probably be superior for that flinch chance. Unlike Night Slash, Bite is capable of actually KOing physically defensive Jellicent after SR, and Celebi as well. That's huge, because before now, Jellicent could easily live a Night Slash and potentially burn Weavile, leaving it crippled and worthless. Going back to Ice Shard, it is important to note that Weavile can now always KO Latios after SR and sometimes Latias after SR and a tiny bit of residual damage. Although 99% of the time Weavile can just spam Bite or Pursuit on the Lati twins, the fact that Scarf Latios can no longer live an Ice Shard and then revenge kill Weavile, is very impressive and quite important. Pursuit KOs Celebi, Latias, Latios, and does a huge chunk to physically defensive Jellicent when they switch out, which makes Weavile the best Pursuit trapper in OU, even better than T-Tar. Low Kick is for Heatran, Blissey, Ferrothorn, and Tyranitar mostly. All in all, this thing is absolutely amazing, and it would make Weavile one of the deadliest assassins in the OU metagame, capable of ripping DragMag and offensive teams to shreds.
Overall, I think Technician Weavile would be an easy A- Rank Pokemon. It still has to worry about being weak to Mach Punch, Bullet Punch, and SR, along with its ass defenses and huge amount of weaknesses, but Weavile would be so useful in this metagame that the goods would outweigh the bads by a long shot. It would easily be a top tier threat.
