I'm planning on picking up the game because I love fighting games, especially team fighters, and the gameplay and character selection looks really fun despite having never seen Invincible. I looked at the character list and was curious on the team building aspects of the game. Is it an MVC-style point/assist/anchor system? If so, which characters are best suited for which positions? Can I just smash three characters together and make it work? Is it assist heavy?
