Silvally-Water, although only recently being used due to defog, is known for surf, parting shot, defog, filler sets. Because the filler is either thunderbolt, flamethrower or ice beam I won't be able to accept the lure. Also, since Qwilfish has low special bulk Silvally-Water is able to beat it with surf alone and then defog if taunt has worn out, meaning Qwilfish is never really used as a Silvally-Water check.

Silvally-Water reliably lures in and threatens Qwilfish with Thunderbolt - while remaining a good offensive threat versus most teams.
Example calcs:
252 SpA Silvally-Water Thunderbolt vs. 252 HP / 0 SpD Qwilfish: 256-302 (76.6 - 90.4%) -- guaranteed 2HKO
+1 252 SpA Silvally-Water Thunderbolt vs. 252 HP / 0 SpD Qwilfish: 384-452 (114.9 - 135.3%) -- guaranteed OHKO (after a work-up)
252 SpA Silvally-Water Thunderbolt vs. 252 HP / 0 SpD Qwilfish: 256-302 (76.6 - 90.4%) -- 18.8% chance to OHKO after Stealth Rock
Hidden Power Electric is standard on Combusken since it also covers Swanna.
Combusken @ Life Orb

- Hidden Power [Electric]
- Protect
Qwilfish can switch into Combusken and wall the physical set and also avoid getting 2HKO'd by Fire Blast or Focus Blast if Stealth Rock are not up. HP Electric allows Combusken to break through Qwilfish since a Fire Blast and a Focus Blast put it in range of HP Eleletric. A lot of Combusken's also run HP Grass or Ice to deal with Gastrodon and Altaria respectively, so Qwilfish is a relatively safe switch-in.
252 SpA Life Orb Combusken Fire Blast vs. 252 HP / 4 SpD Qwilfish: 140-166 (41.9 - 49.7%) -- guaranteed 3HKO after Black Sludge recovery
252 SpA Life Orb Combusken Focus Blast vs. 252 HP / 4 SpD Qwilfish: 153-181 (45.8 - 54.1%) -- 5.9% chance to 2HKO after Black Sludge recovery
252 SpA Life Orb Combusken Hidden Power Electric vs. 252 HP / 4 SpD Qwilfish: 205-244 (61.3 - 73%) -- guaranteed 2HKO after Black Sludge recovery
