w/ Volt Absorb
Timid, 4HP/252SA/252SP, @ Icicle Plate
-Electrify
-Thunderbolt
-Judgment
-Volt Switch
This Jolteon set is pretty neat. The main problem this set has is with priority users, as it is frail, especially in the physical side, which is a problem considering Extreme Speed is pretty common. However, anything without priority is gong to have to play some nasty mind games with Jolteon. I wonder if Substitute could use a slash next to Volt Switch. Lovely Kiss always has a slot on anything that can use it, and it fits nicely with Jolteons set. BoltBeam coverage is really good, although the Fire Plate is also an option for shit like Ferrothorn who doesn't really care for Thunderbolt and can just set-up hazards. A Shell Smash set can be used over an Electrify set, but I think Heliolisk does it better. The only pokemon that I can think of that gives it competition is Thundy-T. While it is slower and doesn't have access to Judgement, it does have more bulk and is stronger, not to mention has a good secondary STAB to use. Not only that, but it has a usable physical attack for Superpower shenanigans if it needs to use that. However, Jolteon is faster and has that magnificent Normal-type to use. It's also not weak to SR which is a big bonus. Overall though, this set is pretty neat, although very reliant on predictions. As a leaving note, maybe it could run a SubPass like it could in Standard? It has Electrify to help with the SubPassing.
w/ Infiltrator
Timid, 252HP/4SA/252SP, @ Leftovers
-Venom Drench
-Oblivion Wing
-Sludge Wave
-U-turn
I'm not entirely sure what this set is trying to do to be honest. First of all, Sludge Bomb definitely deserves a slot over Sludge Wave due to the 30% chance of Poison. Secondly, outside of Sludge Bomb's poison chance, why are we running a special set when Crobat has pitiful Special Attack? I would definitely redo the set to have Gunk Shot (which not has 80 accuracy in Gen 6 and has 30% poison chance) and Brave Bird over Oblivion Wing. Yes, the 75% recovery is neat and everything, but a set abusing that is better off using Nasty Plot with Life Orb. Also, max speed / max attack is better imo. The extra bulk isn't worth losing the advantage of Crobat's amazing speed - the main reason to use it. Honestly though, I'm not digging Venom Drench in general. Yes, the -1 in defenses and speed is nice and everything, but I feel that it is a bit situational, and that Crobat can run something better in that slot like Defog or Toxic Spikes. A Coil set could be interesting as well.
w/ Soundproof
Careful, 252HP/180A/76SD, @ Leftovers
-Horn Leech
-Leech Seed
-Ice Shard
-Spiky Shield
At first I was deeply confused by this set. Why is Abomasnow not running Snow Warning? Then I realized that Soundproof blocked Boomburst, the go-to STAB for Normal-types and Sylveon. The main contender to block is Sylveon, as it also resists Earth Power Judgement, a common coverage move. The EVs look pretty specific, so I won't comment on them. Horn Leech and Leech Seed let Abomasnow get a lot of recovery. Ice Shard is for priority. I'm thinking that Protect is probably better than Spiky Shield, as it blocks status. The damage that it provides isn't that great anyways iirc, so I think that Protect is much better. Substitute or EQ is also an option over Spiky Shield / Protect - one gives you coverage while the other one protects vs status, and you can heal most of the health lost from sub via Leech Seed / Horn Leech. Soundproof also goes well with Sub, as it blocks Sound moves that bypass Sub and Roar.
PokemonMasterDebater's Set:
w/ Natural Cure
Calm, 252HP/192SD/64SP, @ Leftovers/Tanga Berry
-Ingrain
-Baton Pass
-Spore
-Substitute/Giga Drain/Dazzling Gleam (assuming it will be able to learn this)
I'm not really digging this set at all to be honest outside of a baton pass team. In a Baton Pass team it could work decently, but outside of it's not that great. Ingrain Pass is only good on Baton Pass teams because Baton Pass lets you bypass the whole "can't switch" part of Ingrain. Not much to comment on this - it works well on Baton Pass teams but not very good outside of them. A standard set could be something like Recover / Seed Flare / Psystrike or [insert support move here] / Baton Pass or U-Turn with similar EVs to standard / the set's EVs.
The Reptile's Set:
w/ Scrappy
Adamant, 252HP/252A/4SD, @ Kangaskhanite
-ExtremeSpeed
-Power-up Punch
-Earthquake
-Sucker Punch/Crunch
I'll just repeat what I said when I sent this to Eevee
This set is more or less theorymon, but it is literally a better version of its OU counterpart. It could run a Shell Smash set, but so can every other Normal-type. However, Kangaskhan is the only Pokemon that gets a Fighting-type Sword Dance that does damage. Add this with an ESPeed that breaks subs, and you get a huge threat. Sucker Punch is for Ghosts and even more priority, mainly against Ghosts. Crunch can be used if Sucker Punch is too unreliable for you (Shadow Claw can too, but Crunch has more BP). Earthquake rounds the coverage and helps against Aegislash and other Steel-types, as it doesn't trigger Kings Shield. Also, pre-mega form gives Scrappy ESPeed, which is neat.
The only thing I can say is that I'm not sure if max speed or max HP is better. ESpeed means that the extra speed isn't needed and Kanga has good bulk, but base 100 is nothing to scoff at.
