This isn't entirely done, but I am really tiered and want to post this.
Eevee
Normal
95/95/90/85/105/95 (BST 565)
Fur Coat/Adaptability/Scrappy (HA)
Movepool: +Extreme Speed, +Flamethrower, +Fire Blast, +Ice Beam, +Blizzard, +Thunderbolt, +Thunder, +Knock Off, +Surf, +Shadow Claw, +Psychic, +Moonblast, +Double Kick, +Blaze Kick, +Wild Charge, +Fire Fang, +Thunder Fang, +Ice Fang, +U-Turn, +Hyper Voice, +Seed Bomb, +Grass Knot, +Aura Sphere, +Agility, +Growth, +Calm Mind, +Thunder Wave, +Taunt, +Slack Off
Normal types are famous for their very wide movepools. Yet, the "most adaptable" normal type in the game, Eevee, has very little coverage, limited to Iron Tail, Dig, Bite and Shadow Ball. It's about time we fix that. Most of these additions are better for the eeveelutions than for Eevee itself, but Extreme Speed is still noteworthy. While it isn't the most powerful user of the move, it can be the bulkiest. Eviolite+Fur Coat give Eevee 394/648/369 defenses just with HP investment. It also has reliable recovery, so it can serve as a wall if needs be. Just watch out for Knock Off.
I added Growth here because it was an event move for Eevee in gen 2, and I didn't really want to give it SD or NP because those feel very generic.
Sylveon
Fairy
105/65/85/125/145/75 (BST 600)
Fur Coat/Natural Cure/Pixelate (HA)
Movepool: +Eevee's new moves
Not much to explain here. Other than the obvious, *cough*Fur Coat*cough* the only great addition is Slack Off, for instant recovery. Natural Cure can be used to stay status free, but it already has Heal Bell, and Fur Coat is too good to pass up. Additional coverage is always nice, but it doesn't become a massive offensive threat with anything it gained. Maybe a Growth set with Fire Blast and Moonblast/Hyper Voice could work, but there are bound to be better offensive Fairies.
Vaporeon
Water
145/65/75/125/105/85 (BST 600)
Fur Coat/Drizzle/Hydration(HA)
Movepool:+Water Spout, +Eevee's new moves
Drizzleon is great. Scarf or Agility can be used to attempt a sweep with STAB Rain Boosted Water Spout, or
Flareon
Fire
85/145/105/65/125/75 (BST 600)
Fur Coat/Flash Fire/Tough Claws (HA)
Movepool: +Sacred Fire, +Earthquake, +Eevee's new moves
Stats have been adjusted for better bulk and lower Special Attack. anoyingly for Flareon, niether Sacred Fire or Earthquake make contact, therefore they don't reseve the Tough Claws boost. However, Flame Charge, Flare Blitz, Double Kick, and Wild Charge do. The two sets I want to try on this are AV Fur Coat and CB Tough Claws with Sun support.
Jolteon
Electric
85/65/75/125/105/145 (BST 600)
Fur Coat/Lightningrod/Amplify (HA)
Movepool: +Eevee's new moves
Jolteon puts M-Manectric to shame as a fast, physically bulky, mono electric type pivot. The special movepool additions from Eevee make a big impact here, as Jolteon gets BoltBeam+Blast coverage, something that no Pokemon except Rotom-H resists naturally.
PS: We should make more moves/abilities that synergize with Electric Terrain.
Espeon
Psychic
85/65/75/145/105/125 (BST 600)
Fur Coat/Drought/Magic Bounce (HA)
Movepool: +Solar Beam, +Power Gem, +Focus Blast, +Eevee's new moves,
Drought may seem like an odd addition to Espeon, but it is the Sun Pokemon, and it's signiture move in gen 2 was Morning Sun so I'm just gonna role with that. Drought does give it a better way to boost it's Special Attack in Growth, and a psudo secondary STAB in Fire Blast that gives great neutral coverage with Psychic and Moonblast/Focus Blast. Fur Coat makes Bulky CM sets look very tempting as well.
Umbreon
Dark
105/85/125/65/145/75
Fur Coat/Poison Heal/Magic Guard (HA)
Movepool: +Psycho Shift, +Eevee's new moves
Behold, the Great Wall of Umbreon! It is gonna be hard for any attacker to break through without multiple boosts, SE STAB, Mold Breaker, or some combination of the three. The other two abilities are great, but they are outshined by Fur Coat.
Leafeon
Grass
85/65/145/125/75/105
Grassy Pelt/Chlorophyll/Environmentalist (HA)
Movepool: +Eevee's new moves
Attack and Special Attack were switched so that Leafeon would be able to get the maximum benefit from Eevee's movepool. Obviously, Grass/Fire coverage (or as I like to call it, Giga Flame), on a Chlorophyll sweeper is pretty rad, but when you add Ice, Electric, Fairy, Ghost, and Fighting to the list of options, you know that there will be very few things that will be able to hard wall you. Environmentalist looks to me like it would be ideal for Assault Vest sets, with reliable recovery in Grassy Terrain and Giga Drain, and high natural defense.
Glaceon
Ice
Fur Coat/Refrigerate/Snow Warning (HA)
65/125/75/145/85/105
Movepool: +Eevee's new moves
Attack and Special Defense were swapped so that Glaceon would be able to take advantage of Refrigerate Extreme Speed, and mixed attacking sets.
