Fully Evolved Electric Types include Raichu, and the Double Battle Pika Clones... Looks like I'll have to make a
Double Battle Team to not feel not terrible about using them and accept that this team isn't going to be very strong.

Plusle
Plus
-Thunderbolt
-Grass Knot
-Helping Hand
-Entrainment
The more offensively statted of the duo has a moveset that's about immediate effects. Attacking now and support that helps ASAP is always good! Entrainment for use on allies after Minun faints. Probably not much more than a cute gimmick, but then again, Plusle and Minun aren't much more than cute gimmicks. Also, I was having trouble coming up with a fourth move because there's no coverage without Tutors.

Minun
Minus
-Thunderbolt
-Nuzzle
-Fake Tears
-Entrainment
The more defensively statted of the duo gets a moveset about long term effects. Paralysis and a stat change that lasts multiple turns (or ends immediately when you switch ASAP :P) are much more useful in the long run. The main problem with this moveset is if it's just Minun against a Ground type, all it can do is use Entrainment. I guess that'd help highlight why gimmicks are just gimmicks?

Meowstic Female
Infiltrator
-Charge Beam
-Psychic
-Signal Beam
-Fake Out
Female Meowstic learns a lot of coverage moves by Level Up for some reason. Good examples of odd Level Up moves include Magical Leaf, Shadow Ball, and half of this moveset. Signal Beam is used for Grass types and Fake Out is a very annoying tool for Doubles.

Smeargle
Own Tempo
-Electric Terrain
-Thunderbolt
-Nuzzle
-Body Slam
At first glance, there's
5 6 Pokemon that learn Electric moves without TMs or Egg Moves. (Edit: I missed that Exploud learns Thunder Fang.) Smeargle's Sketch technically makes it a
6th 7th. Anilitical mindset aside, it felt like an interesting pick and even though it's not a good thematic for for Electric, it's a good fit for what's turning out to be a cutsy Pokemon team.
Contrary to what you might remember, mainly because Terrain was pretty forgettable before TMs teaching them or the Tapus, Terrain was introduced in Gen 6. (Psychic Terrain, though, wasn't until Gen 7.) Buffing Electric moves 50% and preventing sleep makes it an excellent support move for an Electric Team. Nuzzle is useful without offensive stats for spreading what's praticaly Electric's signature status condition, and Body Slam for STAB (lol, like STAB makes a difference with Smeargle's stats) is because of the Paralysis chance.

Medicham
Pure Power
-Thunder Punch
-Brick Break
-Zen Headbutt
-Acupressure
Medicham is one of the Pokemon that learn Elemental Punches through Move Reminder for some reason, so it's on the team for being one of the few Pokemon that can learn Electric Attacks without TMs. Acupressure is the final move because it can target the user or the ally, making it an interesting support move for Doubles. Medicham is second to last because of the AI porobably being stupid enough to use Entrainment to replace Pure Power.
Medicham doesn't Mega Evolve even though it's Gen 6 because it's not an Electric Type and I'm imagining this trainer as a young kid.

Pikachu @ Light Ball
Static
-Thunderbolt
-Iron Tail
-Grass Knot
-Quick Attack
I like Raichu more than Pikachu, but the Light Ball makes Pikachu viable and using the more popular Pikachu over the much stronger (in theory, not in practice because of the Light Ball) Raichu helps paint this trainer as a cheerful kid.
In game trainers usually only have items on their final Pokemon and Light Ball Pikachu is stronger than Raichu. Even if I ignore that, it'd feel wrong is use a Pokemon that's seemingly stronger than the final Pokemon, but it'd also feel wrong to have a Pokemon I know is weaker than another Pokemon on the team be the final one.
Side Note: Chosing Pikachu over Raichu is what lead to leaning into the cutsy side theme.





This early XY Dex team seems like the kind of team an early game boss would use for a rematch and it's a lot of Pokemon I could see a kid playing with. (Medicham is probably more like a babysitter or an emo older sibbling that's trying to chill but has to deal with people thinking they want to play and be petted because everyone else does. Ugh! No one understands me!) I just went in expecting to be overanilitical, but I really like the side theme that happened to come up.
