Watery Grave is $13; Drowned Catacomb is $8. Fetid Pools & Choked Estuary are $5, Darkslick Shores is $16, Creeping Tar Pit is $4. Sunken Ruins is $18, Underground River, despite innumerable printings, is $8. Polluted Delta is $42 of course. Morphic Pool is $27.

All of these are worse than Underground Sea, which is $800.

But it is also obvious that all of them are good enough that people want to play them, or more accurately, are willing to play them.

What players want is indestructible five color artifact snow lands that also shuffle your library, draw you a card when they enter play, and modal double faced with a Brainstorm/Force of Will split card. Or rather that's what they think they want, because players want to be able to do everything all the time with no restrictions and don't understand that that would make the game unfun.

And like I don't mean to interrupt people talking about what they think the game should look like from a purity of play standpoint, but this thread seems to be specifically framed as "what will Wizards do" and then people keep saying stuff that sure sounds like they don't understand that Wizards only interest in the game is as a means to make money.

It's not enough then to just say you think Wizards should make lands that are equal to or better than the duals for mana fixing, you have to have an actual case for why they would do that.
