Volatile Mox 
Legendary Artifact
Imprint - When ~ enters the battlefield, target opponent exiles a card from his or her hand.
Tap, sac: Add x colorless mana to your mana pool, where x is the converted mana cost of the the card imprinted with ~.
It seems broke, maybe make it so you have to imprint instead of an opponent.

This is actually the opposite of broken, but it is not well put together either, making it approach brokeness from the other side and becoming broken again. And it is weird. Thoughts:
1/ Your opponent can exile a land - great, now this does nothing, except force people to keep hands with more lands.
2/ Your opponent does not exile a land - great, now you just need to play 3 more and you can slap 2-3 Thought-Knot Seer in the same turn.
3/ This is not how imprint works.
4/ The fact that this is legendary does nothing, because it can sac.
5/ This is a free Cry of Contrition, available to every deck. Do not mess with the color pie, yo.

The easiest way to fix would be to exile a card randomly from your own hand or if you want to keep it aimed at an opponent, at least have a you lose 3 life cost involved or something.
If you just exile a card, the broken choice is to just dump that high CMC card you got in your opening hand that you couldn't have used for a few turns anyway.
Oppositely forcing your opponent to choose one of their cards for no cost to yourself is also broken.

Atony1400- that would make it a better Chrome Mox.
Boza- would you also contend that Mox Opal being legendary does nothing?
Discard for that also ramps you is a bit janky. If you are dead set on this card it has to have some draw back that makes up for it. The problem is that the drawback is going to be entirely dependant on the expected CMC to discard to it and therefore the format. Discard for 
is a thing, as is phyrexian mana. So for an expected CMC of 0 paying 2 life to play it would fit into the balance of already existing cards. It gets harder to balance the more mana you expect it to make though. Lion's Eye Diamond makes you discard your hand and that isn't enough of a draw back to getting 3 mana for .

Gidgetimer, yeah, I guess it does.
Maybe make it so that
Imprint - Each opponent selects a card in their hand and reveals it, then you choose one of them to exile (as the imprinted card), then each other opponent discards their revealed card and draws a card.
Sounds sweet, but did I just make it even more broken?

That would make it still broken, because you choose the card. Here is my idea:
Imprint - Each opponent selects a card from their hand and reveals it, then you select any card, then each opponent discards their revealed card and searches their library for any card with the same converted mana cost as the card that is imprinted on ~ and adds it into their hand.
This seems a bit tilted into the opponents' favor, but losing a land is hard on early game, because those 3-4 lands that you thought would stabily carry you into mid game just dropped to 2-3 lands, drawing a card won't guarantee a land.

@Boza The Legendary clause does matter, because you can't play the 2nd unless you're willing to break the first for mana immediately. For example, Lantern Control is a deck that would want to play all of them out at once, but not necessarily use all of the mana at once -- this hinders them from doing that. Stony Silence is another example where you might want to play them all out anyways but can't.
Though, now that I think about it, just playing out a handful of these without using the mana would still make your opponent exile a ton of cards -- that's kindof a problem.
Maybe they exile their card for the imprint, then search their library for a card with the same name and put it into their hand?

I'd make it "add X+1 Colorless mana," lose X life. Then there's high risk high reward and it incentives your opponent to put some value under it.

You are right. This is a VERY broken card. In a discard deck it is at least on par with Thoughtseize, possibly even better.
Even though your opponent gets choice in the matter, it's still a discard effect...which gives your opponents a reason to mana-screw themselves. It's a zero cost discard effect, and when it resolves, no matter what your opponent chooses, the card advantage situation is unchanged and you have either gotten a mana source or gotten them to discard a mana source.
And it costs ZERO. Very broken in the right deck.

Yeah, at the least it should probably enter tapped too. First turn Mind Twist is not very nice.

It would be broken, because the opponent has to lose a land just to stop it.
