Thought of jokingly making this cost and having the ability say "Costs less for each land you control."

Awesome card! I love how it attacks the wrong problem, but might still wreck your opponent. It shouldn't be red, though, since this is, among other things, a Tranquility. Green seems fine, though... especially since it keeps the creatures intact.

I'm pretty sure that as long as it's hurting everyone's stuff, it's fine to be in red. That said, this was originally an design that counted all creatures on the battlefield, but I like the flavor better as an impulsive red decision to destroy all culture.

Note that Jokulhaups and Decree of Annihilation all specifically exclude enchantments. I suppose there is precedent in Apocalypse or Warp World, but I still prefer red to not kill enchantments.

I still support my decision on the grounds of "more precise flavor". If this were strictly an attempt at making a new Jokulhaups, I'd be expected to destroy all creatures as well. But this is about destroying culture, which to me is a more red concept than any other.

Fair enough. I definitely support the cardset designer's right to emphasise certain aspects of a colour's flavour, and to let flavour drive mechanical choices :)

I'll drink to that!

For further elaboration:

All things considered, I'm typically very hard-lined about color-pie decisions, and as previously mentioned this was originally conceptualized as a design. So I'm certainly open to an argument rooted in whether "obsolescence" speaks to a different design and color-choice.

Green's ideal of returning "Back to Nature" felt somewhat appropriate, and thus the multicolored first draft, but I wanted it to convey a certain antagonistic and anarchic mood that was (for whatever reason) best expressed in red.

I've always thought that green was more anti-culture; red is just anti-conformity. This is like a universal Bramblecrush, which feels better green than red.

Huh. So you don't think the Jolrael, Fyndhorn or Naya peoples don't appreciate culture? That can't be right... I think we're confusing culture with cultural trappings. But a strong tendency to riddle, like what keeps popping up in Elven cards in Mirage... that's culture, too. But it's also true that Otarian Berserkers and Mercadian Goblin are chock full of culture as well.

This does raise a question of what green is actually against. It's very easy to say "doesn't like manufactured items", but, obviously, Elves ain't got no problem swinging swords when it suits them. I think green has this thing about centralized power, in any fashion. A farm, for example, is a person's desire to exert his control over nature in order to guarantee his livelihood. The idea that anyone would consider themselves more important than an acre of forest has got to be disgusting to an elf. Green likes community, which separates it from red, but hates leadership, which separates it from white.

In the context of my set's cultural and mythological structure, red is represented by three factions:

The Magdar - Comprised of Minotaurs, Dwarves, Viashino, and some Humans, the Magdar are the oppressed indigenous people of the Southern territories of the country, currently attempting to foment a rebellion against the ruling Empire of Behrun.

The Murans - In the North, there's a mountainous trade route through the Muran Highlands to the neighboring country of Nakarat. This trade route, used by the Behrunese, is commonly attacked by Goblin and Viashino mercenary groups that hide in concealed encampments within the many valleys and perilous terrain of the Muran Highlands. Unlike the Magdar, they aren't a "people" per se, there's no defining culture, they're mostly criminals and outcasts unwittingly serving the Empire by terrorizing the populace on the outskirts of Behrunese territory. (Thus keeping those people in need of assistance from Behrun.)

Fiends of Herat - Lastly, there are the miscellaneous beasts, devils, elementals, and dragons that rule the desert of Herat, which has recently come under scrutiny by the Empire after an archaeological dig unearthed many ruins of impressive technology deep within the wastelands.

In this way, Red is defined (within Melody) as being strongly opposed to the present culture and civilization, as noted in the flavor text. Though the Magdar have a culture that is inspiring their actions, they're also willing to sacrifice that culture if it means revolution. Conversely, Green is found in the Elves of the Ohgun, an isolated monastic culture devoted to the care and study of religious texts, as well as in the farming communities of the countryside.

While molding flavor to suit the mechanics of a card isn't ideal, I don't think that this is THAT far of a stretch. Considering they were willing to print Oblivion Stone, which has never been called a mistake to my knowledge, things can be bent here and there. I would never print "Destroy Target Enchantment" in Red, nor do I think this suggests that I would.
