Clash of Heroes
Instead of using 4 buttons for a complicated control scheme, it may be better to simply use a two button configuration.
Each button will control a hand (LB – Left hand, RB – right hand).
Combos can be added from there. Left Hand plus Magic/Tech attack. Right hand plus left hand can offer power strikes.
It must be decided which is more desirable, as it could affect the entire design of each character.
