Although I’d like to write my own guide on Mewtwo (and I will someday!), I feel as if I would be reiterating things that have already been done well. Here is a good list of resources on Mewtwo. As always, I’ll be updating as I come across them!
- My Smash Corner: Mewtwo Combos & Tricks
- Super Smash Academy: Mewtwo Guide
- Furil (Smashboards Thread): Mewtwo Hitbox Visualization
- Kurogane Hammer: Mewtwo Frame Data
- Abadango’s Mewtwo play: YouTube
- Mew^2’s Mewtwo play: YouTube
