what a thief of mind powers be? :O

A Thief of Mind may steal other’s ideas or strategies. You know that guy you tell some idea to and they’re like “No that’s stupid”, but then they say the exact same thing with a different wording and get all the credit? I’m imagining exactly that. Additionally, emulating others as a facade perhaps, something spy-like maybe? Stealing Choices by planting themselves in the action and being the ones to decide for the entire team, and maybe literally Stealing Thoughts in the sorta creepy Dream Eater sense or like, making others forget stuff.
