Since Black can now destroy Enchantments, and Red has always been able to destroy Artifacts, If or When: Rakdos Disenchant?

Unlikely. Black’s enchantment removal is a clear third in utility.

Re: Rare-B-Gone, couldn't it work in black border the same way Apocalypse Chime and all the other expansion matters cards do, by caring about the original rarity a card was printed at? That way reprints don't impact its effect.

That requires too much knowledge. For example, without access to a database, do you know the rarity of first printing of cards? Does counter target common spell stop a Disenchant? Or a Counterspell? Or a Lightning Bolt?

How do you mechanically differentiate between green and white disenchant effects?

Green overall is slightly better at them, but the base effect is available to both colors. The only differentiation is if it’s used with other effects.

Re fan made cards, I promise I don't intend to toe the line, but sometimes I wonder what level of specifics we're allowed to ask about. Like can I say I want a cheaper disenchant (I do btw) but I can't name a cost? I guess you don't do cost but I don't have another example off the top

You’re allowed to say I want existing Named Spell but at Named Cost. I have little ability to get it to print, but you’re free to tell me.

Hey Mark, have you considered printing a sorcery with flash, but in a Silver Bordered set? To help with as-fan of say, disenchant, e.c.t It would be a good way to satisfy those that really want it while still adding to a set and not just messing with the player's minds.

Just because we can do something doesn’t mean we should. Box filling for the sale of box filling usually isn’t good design.

Hi. I was looking back at many of your previous answers, including to one of my own questions, regarding Disenchant. You’ve been pretty emphatic about its status. I’d be grateful to hear your thoughts about its inclusion in m20 alongside a strictly worse green “Invoke the Divine”. The presence of both together seem to very much contradict colour pie philosophy that you have cited in multiple previous answers. Thanks as ever for your work and willingness to engage.

When one thing is better than another thing overall that doesn’t mean there’s never a set where another color is slightly better in that one set.

Given that White is supposed to only get "Disenchant" effects at higher rarities or less efficiently than Green, could it not be argued that 3-mana instant speed "destroy target artefact or enchantement with upside" like Expose to Daylight of Invoke the Divine is pretty close in terms of efficiency to Naturalize? If mana cost were the only criterion for efficiency then Fragmentize, as another recent print, gets involved in the conversation.

Green supposed to be a little better but it’s not a giant chasm.

Why has the card Disenchant not seen a reprint in a Standard set since 7th Edition? What made the effect to be moved to green in Naturalize? There are still lots of new white card printed that destroy artifacts or enchantments, just not Disenchant itself.

Green is supposed to be primary in the ability, so it and not white are supposed to get the two mana version.

I recently picked up an Ice Age play test Disenchant (super thin, white both sides, that sort of thing). Who all would have played with this card during its use? Not sure where to look to find he Ice Age play test team.

The Ice Age design team was who we call the East Coast Playtesters (Skaff Elias, Jim Lin, Dave Petty and Chris Page). Ice Age is early enough that there wasn’t yet a full development process set up, so besides the design.team, I assume Richard and some very early R&D team members playtested it.

On Decomission, color me confused. I thought Disenchant type effects weren't White's thing anymore. (By Disenchant type effects, I mean destroy artifact or enchantment at instant speed)

White can do it but usually not as efficiently.
