Mana hoser of a different variety

[Norm4eva]

Dogma's Prism
Enchantment   W/G

If a land in play would add more than one mana to its controller's mana pool, instead it adds W or G for each mana beyond the first.  (That player chooses whether the produced mana is W or G.)

I guess I had things like Cabal Coffers and Hide Tide in mind when this card jumped out of my brain.  It seems like it could be either color, since W is all about stupid rules and G is all about playing around with mana.  This definitely also alters things like filter lands and Ancient Tombs and Mishra's Workshop; it's meant to be a strange mana hoser intended to keep other people's mana fixing 'honest' - only in this case, by 'honest' the card invokes the zealot and xenophobe aspects of Green and White, as if to say, "Oh yeah, you wanna make lots of mana yeah?  Well, we do it this way, and if it's good enough for us it's probably good enough for you, yeah?"

It's sort of a retarded Blood Moon, and so maybe its cost needs to be higher.  However, whereas Blood Moon just turns nonbasics to Mountains, this doesn't actually prevent you from getting the intended mana as long as everyone's 'playing fair'.  It's probably pretty narrow, but it seemed neat at the time.  Thoughts??

The wording is clunky. I would really just make it cost 2 and make it give a maximum of 1 mana per land. Much more simple and gives a similar effect.

Whenever a land is tapped for mana, if it would produce more than 1 mana, it produces only 1 mana.

Agreed with this.

Also, a Shop producing  instead of (or a Tomb producing instead of ) doesn't really interfere with MUD at all, since you can still use the colored mana to pay for artifacts anyway.

As one last point: Was it deliberate that this doesn't affect artifacts?

Yeah, you could template this way:

Norm4eva's Prism
Enchantment W
If a land would add more than a single mana to a player's mana pool, it adds only one mana instead. (If a land would produce multiple colors of mana, the controller of the ability producing mana chooses which of those colors it produces.)

But how does this interact with the current understanding of "Mana Source" type effects?

There are no Mana Source effects anymore, that terminology has been dead for just over a decade now. Even if it were still around, I don't believe this would be a problem, since it's a replacement effect. It's kind of like a backwards (and conditional) Mana Flare.

@ bad wording - Yeah, I sort of just spewed the card out without really considering the proper 'Magic: The English' algorithm.

@ delha - hadn't considered the artifact angle at all when I made the card.

It's true that there are a number of decks that don't get punished too severely over suddenly producing what may as well be 'colorless' mana in their deck - but I'm imagining a High Tide player staring at shitty Goyfs or KotRs and going "Well somehow I have to go off but I only really can make    ... hmmm"

As to why it doesn't just axe mana-ramping, I guess for some reason I felt at the time it would be more of a dick move to just turn it all Green, in sort of in spirit of the "our way or the highway" mentality that White and Green tends to go by.  Like, Green doesn't give a shit if all the mana it makes is Green, so why should anyone else mind?  Plus I wanted to be able to 'undercost' the card by giving it just that slight effect on a player, instead of just telling them their Academy was only going to make one Blue mana.  I guess I assumed such an effect would cost more than its actual effect on gameplay would be worth (like in Blood Moon range @ 2G/W)

for the effect Wagner listed sounds fine to me.

The Blood Moon effect is vastly more disruptive and crippling. Blood Moon shuts down probably half the card in your typical Drain control deck until you rip an Island or Sapphire (since your fetches and duals are no longer blue sources). In contrast this card has almost zero effect on the same deck's manabase.

In general cards that stop people from going broken are far more acceptable than cards which actively screw the average deck.
