I main Charizard and Palutena pretty evenly - Charizard is, incredibly, 'okay' in certain (VERY FEW) matchups, particularly when your opponent has never even SEEN someone playing a Charizard before - though I think Palutena is taking over my time priority-wise. She's just a better character in general, and I love how effortlessly graceful she is while being a complete b*tch.
I'd like to see how I handle Mewtwo in this game. He had so much potential as a character in Melee that was never truly realized, and if he suits my playstyle in Sm4sh, I'd love to add him as a secondary (or even replace one of my mains if he's enjoyable enough).
