Black doesn't destroy artifacts.

no, it buries them.

Unfortunately the color pie doesn't work that way.

­Gate to Phyrexia, Phyrexian Tribute, Rats of Rath, Braids, Cabal Minion, Curse Artifact. Also of interest is Murderous Spoils

I'm pretty sure those cards are too old to cite to justify where things belong in the color pie. Except for Murderous Spoils, which doesn't help your argument at all, since stealing is totally different from destroying.

­Braids, Cabal Minion's ability also doesn't help your argument, since she forces sacrifice. Forcing the sacrifice of permanents is definitely a slice of black's current pie, as seen on Undercity Plague.
Suddenly I have a craving for currant pie.

Curse Artifact is specifically designed to hurt your opponent for having an artifact, because black can't destroy artifacts.

Gate to Phyrexia and Phyrexian Tribute hail from a time when "Black could do anything if it was willing to make a sacrifice". That thought process is kind of taboo nowadays. It's a bit like saying "White can do anything, if the opponent gains enough life".

Rats of Rath and Braids are interesting enigmas, eh? They're pretty old... I'd expect something like that from the Rats, but it's surprising to see Braids sacrifice artifacts. One card from the 21st century ain't much of a pattern, though.

Murderous Spoils is weird. I really don't have much else to say, except "What a weird card. I use to play that thing. I thought it was weird then, too."

My beef, though, is the name. Bury used to mean "Destroy target creature. It can't be regenerated". I'm sure you know that... that's why you're making the reference. But bury doesn't mean "Destroy target equipment". Maybe there's a better name that could reference the fact that that creature is being buried with their stuff, without having the card make Melvin cry?

all i hear is intolerance in the face of minor, situational color bleed. it doesn't even directly target the artifact. it's not even any artifact, just a subtype. not only that, the artifact has to be in a specific state in a specific time.

color bleed happens all the time. red and black DO get enchantment removal. blue CAN destroy creatures. white CAN draw cards.

Bury expresses all the flavor of its rules text. The equipment gets buried along with its holder. just like in, murderous spoils, the equipment and the creature are a single entity. there are real world cases where respected warriors, soldiers, and rulers are buried with their favorite weapons and other items used in their lifetime.

Breaking the color pie should only ever be met with intolerance until it is justified.

I personally approve of the callback "Destroy, can't be regenerated" being "Bury" again.

But yeah; this is colour-pie breakage. Whether it's acceptable is for your set to decide really. But this is a VERY efficient spell - always a 1 for 1 trade; often a 2 for 1 or better.

­Murderous Spoils is an interesting point to bring up. Black can certainly Murder a creature; and stealing their stuff sounds like the sort of thing the sneaky side of black sometimes gets to do. So maybe this is ok :)

I think now "Destroy, can't be regenerated" is replaced by "exile", although that doesn't fit the flavour of this card...

Nah, that was "Remove from the game"

Or indeed Remove from the Game, the other card in this card's two-card cycle.

As for this:

> color bleed happens all the time. red and black DO get enchantment removal. blue CAN destroy creatures. white CAN draw cards.

But every single time they're subjected to intense scrutiny. They have to be, otherwise the colour pie will cease to mean anything at all. Certain sets like New Phyrexia are deliberately pie-bleeding, which means they're not precedent for other colour-bleeds. Any colour bleed in sets other than those is very sparse and needs cautious examination, to see whether it's worth it.

of course a single card that bleeds for no reason should be scrutinized, especially if it's overpowered. which is not the case here.

also, an entire set or block of color bleed is a precedent, whether you deny it or not. how can you claim a single card with bleed is bad, but an entire official set made by Wizards can be just ignored out of existence? in other words, why should Wizards be the only people who can experiment with color bleed?

many "official" color pie shifts started from bleeding. vigilance used to white and blue, now green gets vigilance more than blue. green was the first to get fighting, now red also does. red fails at card draw with direct advantage, but get an inferior form in looting. white now get certain forms of counterspells. etc.
in other words, anti-color bleed shouldn't be followed strictly and blindly. even wizards themselves break the rules all the time. so each card and each set should be judged by their own merits, even if it does a little color bleeding.

All of your official color bleeding examples are mechanical bleed, not philosophical bleed. There are different layers to the color pie: the core, which is what each color currently does; and the mantle, which is things that are a bit weird but still make sense for the color; and the crust, which is things the color can do but doesn't. (See Chaos Theory by MaRo.)

@Vitenka: My point was, I thought that, if they want a card that makes a creature go away for good, they're nowadays trying to use "exile", which normally does the job, rather than "destroy" with "can't be regenerated" added. (Hence the big push by Mark Rosewater to avoid cards that bring themselves back if something exiles them.) But looking at gatherer, I'm not sure that was right any more.

thank you Wizards for Silence the Believers (nonbelievers?). er i mean black never destroys, let alone exile auras and enchantments, right? for those who don't follow spoilers, Silence the Believers is a card from Journey to Nyx. It reads like this:

Silence the Believers
Instant
Strive -- Silence the Believer costs more to cast for each target beyond the first.
Exile any number of target creatures and all Auras attached to them.

in conclusion, occasional color pie bleed is definitely fine if you follow the intent and not just blindly follow the color pie.

I would argue that exiling the auras is a bit different from what you're doing here, since those go away when a creature dies anyway while equipment does not. It's definitely a bit of a color pie break, though.

Auras normally go away when the creature dies. In any set but Theros, Silence the Believers would be just Murder (well, Unmake). It's only because of bestow that it actually breaks the pie at all :)

(I guess it also works against Rancor and things. But black can do that too via Cremate.)

Bestow kinda means it's breaking pie even less.

Kill the creature. And, um, that new creature that just appeared? Kill that too.
