The game assigns you a specific deck leader based on your chosen path, and you are stuck with that character for the entire playthrough. The deck leaders and their corresponding paths are:
* Aisha: The "Path of Light"
* Jaden: The "Path of the Darkness"
* Blair: The "Path of Chaos"
Each path has unique storylines, events, and deck compositions. You cannot change these once you start the game.
If you want to play with a different deck leader, you will need to start a new game and choose a different path.
