Other Metagames [SS 1V1]Take only one Pokemon to ladder

[Wss]

My English is terrible, please don't laugh at me.

At first, I just wanted to try this mew, so even the ID was called "t" (meaning test). At last, I boarded ladder with only one Pokemon.

So in fact, my item and EVs are not best choice.I just want to share this set first.

Mew @ Sitrus Berry
Ability: Synchronize
EVs: 248 HP / 8 Def / 252 Spe
Timid/Jolly Nature
- Shadow Ball / Drain Punch
- Fling
- Imprison
- Transform

Imprison + Transform is the core of this set,as long as you use this combo,you can win unless struggle defeat you.
Fling is used to fight against the opponent's Trick,but it need some prediction.
Shadow Ball can break opponent's Substitute,which can prevent your Transform.
Drain Punch can help you 2HKO Darmanitan,you can choose it replace Shadow Ball.

I've tried to change EVs to avoid being 2HKO by some move,but i still defeat by struggle,so i finally choose 248/8/252.
If you found better EVs,I hope you are willing to share in this post.

There are some replays show how this combo works.
