Nonland is probably the safer bet. Either way it's still a very fun effect just to wipe everything, friendly and enemy alike

I mean, without nonland... You have an empty board, and I have a 10/10 indestructible. There may technically be ways to escape that, but it wouldn't make for fun games.
Excluding lands opens up lots of opportunities for your opponent to just exile it before you ever get a chance to attack with it. The 10/10 body doesn't have trample and is even counterable. If your opponent manages to draw creatures, they can stall until they draw a real answer.
Yeah, and I think that counterplay is necessary for fun games. I mean I might let it go to play test as is for shits and giggles, but I think it should be nonland.
I just think it needs a bit more if it only hits nonland. The other versions of Ulamog are 10/10 Indestructibles that provide a lot of value when they attack, even if chumped or if their cast trigger never went off.
I suppose that's true, but they also only hit 1 or 2 permanents. And if you're building around this one, you can phase stuff out or flicker it until eot for a big rift that can't be rebuilt. I'm thinking like Teferi's protection
I mean at that point you're spending ~15 mana to win the game, which... you can already do for less mana with other cards. Insurrection, for example.
True. But that's also vulnerable to counterspells and disruption...
Like I said, I think it can be playtested, but I also think it might be too strong hitting all permanents.
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.
