Persona themed card game

Pretty simple. I’m working on a persona themed card game.
I just need ideas for more mechanics.

I don’t have any art for it currently but I’m working on it.

In general.
It’s a turned based combat card game.
You start with 3 cards, one of 4 types:
Defense
Support
Offense
And persona.

Support cards don’t end your turn so you can use those as much as you want.
After each draw, you gain MP.
You can only draw cards when your hand is empty, or refill your hand manually by ending your turn early.
If you end your turn early, you gain 5 additional mp per unused card.

I plan to add:
Specific person abilities
Menus
Items
Specific enemy types
Status effects
And the likes

But thoes are pretty standard obviously.
I want to have this have its own unique mechanic.
But I don’t got any clue what to do.

I was thinking maybe some kind of persona charged ability?
Like, using your persona adds to a charge that can have some kind of effect when filled or something.

Idk.
Not many ideas.
I’m probably not going to just copy any story from a current persona game but I’ll definitely use some ideas.

I do also plan to make any visuals a pixel art style.

Here’s the .wick of the general mechanics so far. Once again. No proper visuals.
