Stuart's Tenet

If something has happened before, they can make it happen again by referencing it (either repeating itself again in real time, or by creating an "illusion" in real-time on the battlefield). Works better with something that happened further in the past, though not to say something sooner wouldn't work, it would just be harder to accomplish. Can force people to justify their actions, even when they don't want to.
Drawback: The more "grand" the action being recreated is, the higher the dice roll needed it is to accomplish. Usage of this ability is based upon "Spell Slots", starting at 2 at level one, then increasing by 1 each subsequent level.
