So I recently created a new OU team centered around Swords Dance Aqua Jet Feraligatr sweeping, but a decent EV spread for this type of Feraligatr isn't on smogon. The SD set still only features Waterfall, so the EV spread is just 4 HP / 252 Atk / 252 Spe with a Jolly nature. However, with priority, Feraligatr doesn't need so much speed, and can just opt for more power. The set I've been using to great success is this:
Feraligatr @ Leftovers
Ability: Torrent
Nature: Adamant
EVs: 40 HP / 252 Atk / 216 Spe
Swords Dance
Aqua Jet
Ice Punch
Earthquake
I invested enough speed EVs to outspeed defensive Celebis (neutral speed nature, 32 Spe EVs), as well as most variants of defensively-orented Zapdos, all variants of neutral speed natured Brelooms, and pretty much every standard variant of bulky OU waters other than Starmie. Since these are the major counters to the average Feraligatr, I wanted to ensure I could get the upper hand. For example, if Feraligatr SD's as defensive Celebi switches in, I can get a clean 2HKO with Ice Punch after living one Grass Knot. The same goes for defensive Zapdos, although I don't usually keep Feraligatr in as Zapdos has a chance to 1HKO with Thunderbolt. Breloom goes down to Ice Punch easily, and being faster than bulky waters lets me get off more Earthquakes. Also, before anyone says anything, I opted for Leftovers over Life Orb to prolong Feraligatr's life on the field, I usually get 2 SD's off on average thanks to Leftovers recovery, and I prefer survivability over power. I can't name how many times I've used setup sweepers that only end up getting one attack off before dying to LO recoil. Anyway, I'd mostly like the EV spread to be rated. I've been considering just going for a simple 252 HP / 252 Atk / 4 Spe, so some feedack on that would be nice as well.
