Dont use this:
Feraligatr @ Life Orb / Lum Berry
Trait: Torrent
EVs: 252 Atk / 4 Def / 252 Spd
Jolly Nature (+Spd, -SAtk)
- Dragon Dance
- Waterfall
- Ice Punch
- Earthquake / Crunch
Instead use this:
Crawdaunt @ Leftovers / Life Orb
Trait: Adaptability
EVs: 4 HP / 252 Atk / 252 Spd
Jolly Nature (+Spd, -SAtk)
- Dragon Dance
- Waterfall
- Crunch
- Substitute / Superpower
Fera DD have no double stab, less attack and worst ability for this set which means that is outclassed by Crawdaunt since this have a better ability to break by the reasons mentioned, the worst speed and bulky isnt a deal for Crawdaunt since have a nice type that help to setupp on common mons like Slowking, both of them should be outrunning by common things like Rotom-Cut Scarf. While the different of power between both is very notorious. If you wanna use Feraligatr just run a SD versions because is bulkier and better because also take advantage of Torrent with Acua Jet + Waterfall and you can run like item Mystic Water, when Sheer Force gets released in Feraligatr will be another story totally diferent. After of this I should to say that DD Crawdaunt is better because the offense presence doing a lot of damage with Waterfall and Crunch. Anyone know that Crawdaunt is a pain for stall teams that lacks of Tangrowth / Poliwrath / sometimes Ferroseed.
