Answer 1

Gen 9 NU Nasty Plot

Mew @ Leftovers
Ability: Synchronize
Tera Type: Fairy
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Nasty Plot
- Psychic
- Earth Power
- Draining Kiss

A Nasty Plot set Mew can use in Gen 9 NU. Nasty Plot boosting Mew's Special Attack allows it to become a potent wincon that can easily break down balance teams and be tough for offensive Pokemon to deal with. Psychic is used for the Psychic STAB since is a consistent powerful STAB. (Plus, Chansey is no longer NU now) Earth Power is used to let Mew hit Steel-types such as Magnezone, Registeel, Copperajah, and Klefki super effectively. Earth Power also allows Mew to hit Alolan Muk, Chandelure, and Incineroar super effectively. Draining Kiss lets Mew hit Dark-types such as Krookodile, Brute Bonnet, and Umbreon super effectively, and it allows Mew to have HP recovery. Leftovers gives Mew a little HP recovery each turn. Tera Fairy is used so Mew can resist Dark moves. Tera Fairy is also used to boost Draining Kiss' BP from 50 to 60 so it can deal more damage and heal more HP, making it harder to wear down Mew.
