For Challenge # 052 Evil Maro sez: "It's more expensive than Temporal Aperture, which was a fan favorite. But in exchange for the extra cost, you have the option to hold cards flipped in the exile zone and potentially play them later. For example, if you flip a Cancel, you could use it later by activating 'Make Your Own Luck' later, and you'd still get to exile another card! Sure, it's pricey compared to the Aperture, but we're sure players will find many uses for this card."

Hmm. The comparison to Temporal Aperture invites one to notice that this doesn't shuffle. So you can Brainstorm or Top a particularly tasty card to the, ah, top. But even then you've paid at least 11 mana, and need to have found one of your expensive win conditions. Is it that strong to get Emrakul, the Aeons Torn on turn 6...? I mean, yes, of course it is, but Polymorph decks were just an outside player when Emrakul was in Standard.

Or is it the way that this doesn't say "an exiled card you own"? You can nick the card off an opponent's Chrome Mox or Isochron Scepter, both nerfing their artifact and getting a free spell yourself. If they're playing Legacy and have cast Force of Will or Demonic Consultation, so much the better. That seems more "cute" than "broken" though, since again, you're paying 10 mana for it...

Both, but my big dig was the ability to cast the same exiled sorcery or instant over and over again, if it exiled itself. Oh, and at instant speed doesn't hurt.

Funny thing is, it's true, this is only 'theoretically broken', in of the fact that it does a bunch of things it shouldn't be doing for much cheaper than should be happening. But would the card even crack standard? Yes.. oh, yes it would. But would that break the environment... I couldn't say.

I do know that part of my comparison to Temporal Aperture was a bit of Evil Mark Rosewater slight of hand. Temp. Ap. isn't a fair card... it only seems fair when compared to the rest of the Urza Block. How much would you pay to draw a card? Jayemdae Tome is too expensive, sure, but that's one heck of a discount.

Ah, I see! Yes, I think that is a really good, idea, but I don't think that's what the wording on this card does. I think "cast from exile" is just the normal wording meaning "from exile, put it on the stack, then it goes to the owner's graveyard as normal"? I think to cast it repeatedly you need the "copy it, you may cast the copy" wording which wouldn't be out of place, although it might be harder to make the oversight look like a place.

Then it's a bit like Panoptic Mirror, except that you have to pay every time, but get a lot more flexibility.

Oh, no, I was doing it the right way in my head. The idea was that the spell would keep exiling itself on resolution because what it did was too powerful to keep kicking around. Make Your Own Luck would just use the fact that it exiled again and again and again to it's benefit.

Want an example? How about Time Stop. If you wanted to be a little more (questionably) fair, you might use Diminishing Returns (though, I admit, that card's a bit too old to worry about).

Ah! Sorry, yes, you're right, that's quite a good interaction, two supposed safety-mechanisms interacting to make a powerful spell recurse as many times as you want.

Time Stop "works," but the card you're looking for is Time Spiral.

Time Spiral is a broken card to begin with. It already has a number of enablers. Time Stop every turn, however, is a hard lock against some decks, and was reprinted in Tenth Edition. that being the case, yeah... that and/or Memory Jar would be pretty insane.

Edit: Holy! Memory Jar doesn't exile itself? What the 7I&$ were they thinking?
