Apparently I haven't...

I could include more restrictions, like saying instantaneous teleportation can only be achieved after "contradiction" has been unlocked and that your character would only be moving towards or away from things rather than going anywhere instantaneously. Or I could say there's an absolute limit to how many 'spells' your characters can cast or the scope at which they can be cast, but I'd rather not. I don't want to make a rules-heavy gaming platform like D&D.

I think player intent is important. You don't seem to intend to want to break the game, the simple fact that you seem to be afraid of creating a character that's OP is enough to make me trust that you won't be OP. I trust that once we start, you'll be in-character, and not many teens are Machiavellian game-theorists who will exploit every possible rule and exception they can get their hands on in order to achieve absolute victory at any cost. (unless you're Ender Wiggin)

My two-cents, but if you're still uncomfortable with the idea, better go with a different dichotomy.
