Most Rotom-W carry Volt Switch so SubDos is not going to have a problem.Use DD on the switch you force and then sub up as Rotom breaks your sub and switches out.Not many things can take a +1 Gyarados with rain up...
Just a nitpick but strangely Kingler doesn't learn Waterfall.
Also i think Scarf Crawdant is much better than Scarf Kingler and generally is a good option to easily 2hko Ferro and hit stuff hard.
He only hits 343 speed with a scarf and a positive nature but he makes up for it with his awesome wallbreaking power.
He has 339 attack with a neutral nature.Add Adaptability and Rain in the mix and his Waterfall is really powerfull.
I can't do calcs right now but i am sure that even resistors are in trouble.
EDIT:I did some calcs and here are the results:
Rain boosted Waterfall vs Latios : 508 Atk vs 196 Def & 302 HP (80 Base Power): 223 - 263 (73.84% - 87.09%)
Rain boosted Crabhammer vs Latios : 508 Atk vs 196 Def & 302 HP (90 Base Power): 249 - 294 (82.45% - 97.35%)
Rain boosted Waterfall vs Starmie : 508 Atk vs 206 Def & 261 HP (80 Base Power): 211 - 249 (80.84% - 95.40%)
Rain boosted Crabhammer vs Starmie : 508 Atk vs 206 Def & 261 HP (90 Base Power): 238 - 281 (91.19% - 107.66%)
I made this calcs to show that classic offensive water resistors tha may give our team troubles are potentially ohkoed with a resisted move.You don't even need to predict and go for the Crunch many times.
So scarf Crawdant is definitely an option to consider as a somwhat speedy revenge killer that acts as a wallbreaker at the same time.
And he also deals with our most common problems like Ferro,Gastro and Latios.
Why not just use DD Crawdaunt? x_x
Getting that free turn might be tough, but it's apparently worth it with a LO.
