Quick note about the EVs: If you would like to survive 5 hit Icicle Spear from Loaded Dice, you may use:
EVs: 168 HP / 96 Def / 244 SpA
Lax Nature
(This is my first time doing this so forgive me if I'm misunderstanding how this works, also I goofed the EVs/calcs like 17 times so hopefully its right)
This took me forever to find a mon that can swap into Weavile and take advantage of it staying in. I started my search by looking at mons on the viability list that Weavile dunks on usually. At first, I started messing around with max phys bulk

with jaw lock dragon dance and fighting tera tera blast/focus miss

, but it was too reliant on tera to work. Ideally, I would like my lure to work with/without tera. Finally, I landed on:
Now, surely this dumb little dragon dies switching into a 80-120 base power ice move right? Wrong.
252 Atk Weavile Ice Spinner vs. 168 HP / 80+ Def Kommo-o: 174-206 (52.2 - 61.8%) -- guaranteed 2HKO after Stealth Rock
252 Atk Weavile Icicle Crash vs. 168 HP / 80+ Def Kommo-o: 186-222 (55.8 - 66.6%) -- guaranteed 2HKO after Stealth Rock
252 Atk Weavile Triple Axel (40 BP) (3 hits) vs. 168 HP / 80+ Def Kommo-o: 258-312 (77.4 - 93.6%) -- approx. 2HKO after Stealth Rock
Well, it lived (barely, like there's maybe 4 evs of leeway to survive switching in while rocks are up). Surely

just clicks Ice Shard now right?
0 Atk Kommo-o Upper Hand vs. 0 HP / 0 Def Weavile: 436-516 (155.1 - 183.6%) -- guaranteed OHKO
Upper Hand will go before Weavile can attack with Ice Shard and OHKO if it is not holding a Focus Sash. Now, what if you are worried about Focus Sash and you are not running Stealth Rock? Well, thats where the second option for the held item comes into play. It reduces the overall strength of Kommo-o after Weavile is gone, but guarantees a KO against Focus Sash Weavile without having to play Upper Hand vs Vacuum Wave mind games. I considered Rocky Helmet, however, there is always the slight possibility of Protective Pads or switching into an Ice Shard (non-contact move). Jaboca Berry is activated by ANY physical attack, is eaten by the holder, and inflicts damage equal to 1/8 of the opponent's total HP, therefore it will activate on Ice Shard.
I must state that this isn't consistent, but even if they switch out immediately, you now have a +2 Atk and +2 SpA Kommo-o that can at least get a Vacuum Wave off. I do believe that many would not consider Upper Hand at all and immediately use Ice Shard though.
