12 mana: win the game. A friend said it should probably be nonland, and yeah that’s probably the right move. But as a first draft, it’s just not as exciting.

If we’re talking about Commander, which is really the only place this would be strong at all, everyone else is also running Teferi’s Protection effects… or Stifles, which effectively counter it, or a normal counter for your Teferi’s Protection effect, or whatever else. As soon as people see you casting Teferi’s Protection main phase with 12 mana in your mana pool they’re going to know something is up, and they’re going to stop your bullshit if they can.
I mean, I wouldn’t cast protection until the trigger is on the stack about to resolve, prolly. And I’m not imagining this is hard cast all that often. Casting for free still triggers it.
That makes it even more vulnerable to disruption… If you cast Protection first, and it gets countered, you just… don’t cast this. If you cast this first, your entire board gets exiled (and it presumably also gets countered, or someone just floats a white and Swords to Plowshares it once it resolves).
Really, that alone is the biggest reason to change it, not because that’s too powerful, but because I think if I was at a table and someone exiled everyone’s permanents and then didn’t win the game on the spot (or present a foolproof path to victory in a turn or two), I’d never play with them again.
