So I always wanted to bring Jynx in line with Magmar and Electabuzz... by evolving her.
Coldmama
Type: Ice/Psychic
Ability: Refrigerate/Cold Snap (when struck by ice, take no damage and speed up) Dry Skin (HA)
Stats: 80/40/60/135/110/115 (540 BST)
Keeping in theme with Vire and Mortar wasn't easy. After all, they lose speed but Jynx was actually fast once upon a time so the stat to go down by 10 would be either Attack, Defense or SpDefense.
Evolution: Evolve Jynx with a Freezizer and trade it.
Design: Compared to Jynx, Coldmama is slender, more like a rich millionaire in her apprearance with a sparkly red dress and slender arms.
Competitive Use: Coldmama is to be the Jynx we always wanted to use effectively. With refrigerate, you could us Hyper Voice, sure, but you could also use, get this: Wring Out. As an opening move, it has 132 power before STAB and an Ice typing against a full health foe. Sorta gimmicky, but a powerful one. Coldsnap helps if you want to speed up in the ice. Then again, you'll probably want Dry Skin because the added survival of Rain Dish AND Water Absorb combined is a welcome thing to have.
Harmonian Spoink and Grumpig
Type: Ground/Grass
Ability: Thick Fat/Leaf Runner (Doubles speed in Grassy Terrain), Muckraker HA(Doubles speed in Toxic Terrain)
Stats: Same as Spoink and Grumpig, except their Attack and SpAtk stats are switched.
Evolution: Lvl 32 just like normal form.
Design: Besides the more muddy look, the 'gems' that both forms have are replaced with muddy apples or cherries. It doesn't eat them, instead it uses them to attract challengers to beat them up. It has tusks.
Moves: Take Away all psychic moves except Psych Up, Trick, Recycle and Zen Headbutt (only from tutor) as well as Shock Wave and Thunderwave. Instead add many grass moves including Leafage, Seed Bomb, Wood Hammer, Leech Seeds and some powders. You can also include Earthquake, Drill Run and some Rock moves as well as Fire Fang and Ice Fang and finally Drill Peck. Also add Growth, Play Rough and Sword Dance as well as Poison Jab and Horn Leech.
Competitive Use: Do you remember Grumpig? I barely did. That's why I wanted to give a non-mega Grass type Thick Fat and a decent secondary STAB. Then again, abusing terrains with 80 Speed is more than a viable thing to do. A Grass type Toxic Terrain abuser can help stop the Ground Types that try and cock-block it.
Harmonian Frillish and Jellicent
Type: Electric/Poison
Ability: Levitate, Recharger HA (Rain Dish for Electric Terrain)
Stats: -10 Atk, +5 Def and SpAtk both forms
Evolution: Thunderstone
Design: Gamefreak has done a good job avoiding the Electric Jellyfish trope. Pity I'm not as resistant.
Moves: Taking away all water moves besides Surf and Rain Dance, and all ghost except Ominous Wind, Night Shade and Hex while adding many Electric and Poison moves including Toxic Spikes and both STAB terrains. Gets a new Signature called Paralytic Venom**.
Competitive Use: Floating Poison/Electric is like giving Jellicent a new chance in the meta to be useful. Then again you could choose recharger, though as it turns out, Giga Drain isn't a terrible Coverage move when both your STABs are resisted by Ground types. Ice Beam, then again, helps with ground types who have a grass resistance most of the time.

Paralytic Venom
Type: Poison (special)
Power: 90
PP: 10
Effect: Has a 30% chance to paralyze.
Makes Contact!
Yes, except since they're flying the terrain doesn't affect them so they don't lose an immunity.
If you have a terrain that grounds everything it removes the point of it being a terrain over a weather.
Keep in mind, terrain wars can also cancel this out quickly enough. The logic behind the idea is that the rocks go high enough to 'ground' the singly airborne mon with a mountain.
It gives Rotom-Fan a huge leg up on everything!!
Speaking Rotom... new forms?
Rotom-R (
Robot Action Figure)
Type: Electric/Steel
Ability: Levitate
STAB: Flash Cannon
Competitive Use: Floating Electric/Steel type. Otherwise it has a Rotom theme to it.
Rotom-D (Anamatronic
Dragon Toy)
Type: Electric/Dragon
Ability: Levitate
STAB: Draco Meteor
Competitive Use: It'd probably be seen as a superior Rotom-H if Fairy didn't exist.
Rotom-G (
Gas Machine)
Type: Electric/Poison
Ability: Levitate
STAB: Sludge Wave
Competitive Use: Kinda like Weezing but with added resists? Maybe?
