First, I think mistakes are inevitable, especially with a card pool the size of Magic's. Adding more testing would not catch every issue. But I agree that adding more testing would catch more issues.
My point was that they are trying to push Standard, and their attempts to do so via new printings (rather than bringing back old staples like Bolt, BoP, StP, etc.) could be expected to have ripple effects in eternal formats even if they were taking seriously their duty to test cards for Standard. [12:40 PM Edit: And they obviously aren't.]
Moreover, Wizard's statements have at least suggested that they don't test for eternal formats at all, both now and in the years past when there were fewer mistakes. If that's true, it would be erroneous to say that the increases in bannings and restrictions stems from them getting sloppy or too relaxed when it comes to testing for eternal formats, because there would be no difference in the amount of testing between the past (0) and the present (0). And if that is correct, it's difficult to tell whether the increase in mistakes in Vintage can be attributed to the failure to adequately test for Standard or simply to the push to increase Standard's power.
Even if they were sufficiently careful such that their attempts to ratchet up the power level of Standard didn't lead to mistakes that require bannings within Standard, the additional synergies and lines of attack available in eternal formats means that any attempt to push Standard's power level makes mistakes in non-Standard formats nearly inevitable.
That would be true even if Wizards did their best to test and QA for those formats, and let's not forget that Mark Rosewater has publicly stated that Wizards does not "have the means to test older formats".
Yes, that is absolutely correct - these cards are not part of anyone's collection, they are only accessible in the preconstructed deck event, and they will not be accessible to anyone after that event ends.
However, as @Aelien pointed out, these cards are not only functional (granted, none of them are super complex) but several of them are also animated, including at least Mox Pearl, Mox Sapphire, Sol Ring, and Black Lotus (not sure about Ancestral Recall). Given that the preconstructed deck event is a short-term promotional event, it seems odd that they would devote animation efforts to these cards unless they have at least an inkling that they may bring them back for a more sustained outing at some point.
In case everyone missed it, there are some real vintage cards - Black Lotus, Moxen, Ancestral Recall, Sol Ring - in the current free Arena event (an "Ashiok versus Elspeth" pre-constructed deck event to promote Theros: Beyond Death). It was quite startling to open a starting hand with Ancestral, Black Lotus, and Underground Sea in the Arena client.
I would not be surprised if they bring a Vintage Cube to Arena at some point in the next year or so, though obviously the reliance on bots would be a weakness.
@brass-man I know there is the "Stitcher" App - it's referenced at the end of some of the podcasts I listen to (e.g., "Find this podcast on iTunes, Stitcher, and wherever else you find your podcasts"), but I'm not sure if there's a separate submission/aggregation process for that app.
@ten-ten It won't happen until maybe it does happen. It's open design space. Literally the first thing they did upon abolishing the planewalker uniqueness rule is to create a planeswalker that can duplicate himself. At some point, it's likely that they will create a low-power planeswalker that has no legendary subtype at all. "All" means "all" only when it doesn't mean "all except for one or two," but Wizards often means the latter.
@necrogeist said in Why I don't think Mishra's Workshop should be restricted.:
Given the presence of the B/R list and the public knowledge that any card may be banned or restricted in any format, there is no reasonable reliance interest in keeping certain cards from being restricted.
Yes there is, because deliberately printing cards you know you need to ban/restrict is poor game design, and pointless. If they believed in your poor game design and actually made purposely broken cards they knew were going to be banned in all formats and restricted in Vintage, they would just outright destroy Vintage. It's already quite heavy on variance and singletons.
This is a fine argument against printing such cards, but that's not a legally cognizable argument.
In fact, given that there are constant new printings of cards, you couldn't maintain a cause of action if they printed Mishra's Double Workshop that taps for 6 - you know there are going to be new printings of new cards that may obsolete your reserved list cards.
But this card is dumb and will never happen. I'm not sure what point you are trying to make? It's not like they are going to print moxes and duals that are just upgrades to original alpha design.
I'm not 100% sure, but i think that printing strictly better versions would actually qualify for 'functionally identical'. If it does exactly what the other cards does plus something. I mean they haven't made an upgraded version of Thunder Spirit even though they play with that space.
There are non-reserve cards that are better than reserve-cards, but they do not technically function the same (due to mana, mostly). Show and Tell is much much better than Eureka, for example, but is not a 'functional reprint' that breaks the reserve list policy. I think printing identically Eureka at 1G would be blatantly breaking the spirit of the reserve list.
The point was that the reserve list is a discrete and limited promise - Wizards will not make functional reprints of cards on that list. That's all they promised, and that's all they could be held to.
