Kind of like Pithing Needle, kind of like Nevinrryal's Disk. Not sure about having two board wipes at Mythic (this and Heaven's Arrival), but the uses are kind of different, I guess?

­ for a colorless nonland permanent board wipe seems about right for the most part, since that's how Oblivion Stone is costed. Not sure about the cost reduction clause (sort of balanced by the cost, sort of balanced by the fact that you can't cast the card until you activate the ability first), especially due to the text space.

I also want this to be an enchantment for flavor and tutor reasons, but it might be a bit too odd and jarring.

If you want it to be an enchantment, why not have it be or ? I really dislike these true color breaks however excused artifacts and mythic rarity may be of that.

I guess this goes back to the discussion of whether or not artifacts should have access to abilities that are traditionally not found in certain colors? I costed this similarly to Oblivion Stone (assuming activating immediately; board wipe activation is a little higher due to the utility this has in just sitting on the battlefield). Personally I think mass board wipes is well within the "colorless" color pie. If there's a good argument why mass board wipes shouldn't be in the colorless color pie, I'm all for it. I'd probably just shuffle this off to a second-set mythic if I did change it to an enchantment.

Okay, so and have access to board wiped now? That's greeaaat. We might as well reprint Nevinyrral's Disk. Eh, screw it - why stop there? Let's just make all cards colorless!

God. Darn. Artifacts. I hate them sooo much.

/sulk

EDIT: Holy crap!? Does that say "nonland permanents" there? I thought it said "creatures". OMG I can't handle this. I-I'm out, man.

Eh; + is probably a reasonable cost for a nevs disk effect.

Also having the other effect, of allowing you to use it to ban a specific card - that combination probably needs upcosting a bit.

But yeah, artifacts are kinda kooky colourwise.

@Vitenka, I mean, in any given game, it's either going to be an O-Stone that requires to have a creature in hand, or a overcosted Pithing Needle, right? I'll adjust it to 2-7 so it's more in line with Perilous Vault's cost.

@Tahazzar, I realize you're only being semi-serious in your complaints, but I feel like board wipes at 4 through 9 mana are always in the pool of abilities that artifacts have access to. At 4 mana you have limited/temporary board wipes, like Boompile or Aligned Hedron Network, while at higher (technically higher) levels you have All is Dust, Perilous Vault, and Oblivion Stone.

Artifacts have always existed in this state where they have slightly overcosted or more inflexible versions of color-specific abilities, too. If you limited artifacts' ability pools to "all colors must be able to do this", I imagine that artifacts in general would be stone unplayable or boring. And I feel like, in order for mono-color decks to exist in any given format, there should be a number of artifact-specific tools that decks can use without being forced to branch out into other colors, as sideboard cards or otherwise. But I'm also a fan of Hornet Sting and Chaos Warp's existence (though obviously not for a place in Green's color pie), so my view on the color pie seem almost antithetical to yours. Not to mean any offense, of course.

What if you instead added more colors to it rather than removing any? Like, this would be a neat card. Getting access to more flexible answers is one of the reasons why people add more colors to their decks after all. Colors / color pie is cool, let's keep it that way ;)

I don't like encouraging those Urza's and Locus landed decks.

Personally, I don't think that "just splash {color} to get X effect" as a single solution to getting access to effects is a good design principle. In terms of metagaming, I'd much rather the player be able to choose consistency (splashing a color) or cost (using costly artifact spells) when deckbuilding, especially since a lot of players already dislike the inherent lack of consistency that the land system already gives them.

That being said, I completely misremembered what Pithing Needle actually did. This is now a Mono- card, in line with Nevermore and Planar Cleansing.

This is the only "seal" in the set that isn't an Aura Seal with an unseal cost...

Yeah, this was made before the Seal name change. Working on an alternate name.
