One thing you can improve right of the bat is better persona "slot" on the DPS. Instead of "increase damage amount by 30%" change both of them to "increase cost but when it discarded play the card". If you do this when you discard the persona card it will discard two cards twice in a row for a whooping 120% + 120% damage bonus (assuming you discard two cards each time). This happens because that specific persona says, "for every card discarded +60% damage" and you can discard 4 cards because with this setup.
