I would love to see more interesting mechanics, Enchantments could possibly work but I think that they would be too much work to keep in check so that the balance of the game doesn't shift too much. Maybe some minor changes to the board that last until the end of the game. Because if we get to interact with Enchantments that could bring too much complexity without giving enough value to the gameplay experience.

It is a nice idea nevertheless, but there is so much to think about before someone finds a way to implement this in the way it feels like it belongs in the game.
