Hmmm I am interested. Actually you said persona, so the question is in Gwent and MTG, they have Planeswalker and Leader cards. An interesting concept would be having the alternative self of them as leader cards? Is this the jist of the Persona half of this RP?

I'm not familiar with Gwent, but the 'persona' is the battlemage profile basically, the ancient battlemage  that your character becomes when doing battle. The best way to explain it is that everytime you initiate a battle its not played on a table but taken to a 'shadow realm' where the cards become real creatures when summoned, the battlemage is your avatar of that realm.
