To use shedinja properly you need to know movesets fairly well.
If the AI pokemon cannot touch shedinja, it will switch to one that can, so if they don't switch, it means they're done. This is buggy with the move nature power, you're fine outside of caves (ghost).
Do not use shedinja against weather setters, a pokemon using hail is the same as a 100% accuracy sheer cold.
I like spite because more often than not, you're likely just PP or toxic stalling if you're using this, your shedinja will probably be underleveled.
If the enemy pokemon has pursuit, your shedinja will die.
Do not lead shedinja in normal gameplay, if you don't know what it's leading against, it stays in the back.

Shedinja wins and loses on moveset and ability, it's not something that sweeps traditionally, it's a scalpel you can use as a get out of jail free card on many pokemon.

use the zoomercore hardcore nuzlocke strat of turning the entire game into a spreadsheet and referencing it obsessively

see I thought about double team but I dont know if it would be worth investing in if he could still just get one shot on the next turn. shadow ball wouldnt do a lot of damage because of his weak stats

I thought about using goggles?

Protect
Baton Pass
Toxic
Swords Dance

Assuming you play on SET it's a great pivot.

As >>59584092 said, you need to make the entire game garbage but giving the player very limited options, from which only an extremely small subset of them lets you win against certain trainers, while anything else leads to a loss.
