Land Designs

I already made the perfect entry for this a while ago. It's gonna be hard to come up with something new. Entry loading...

Murder Scene
Land
: Add .
Whenever you investigate, you may untap Murder Scene.

Bountiful Vineyard
Land 
, : Add one mana of any color.
Whenever ~ becomes tapped, you may pay . If you do, create a Food token.

Thx for the win.
The next challenge is a Dual Land whose drawback isn't mundane.

I mean mundane is that

1. Simply requires life ( pain land, shock land, fetch land etc )
2. Simply enters the battlefield tapped
3. Is legendary
4. Doesn't have a basic land type

Note that

1. You may post a virtually dual land like a fetch land. If it can be counted as two color land, it doesn't necessarily produce two types by itself.
2. You may post a land cycle if you want.
3. Requiring life in very weird style or EtB tapped with a brand new way of avoiding tap-in are allowed.
4. But note the core point of this challenge is that I want to see a dual land with a new taste. I heavily valuate the innovative spirit in this challenge, though I can not say that the most innovative one must win.

I thought of doing something similar to this cycle of lands, except it's based specifically on the basic types for the colors it produces.

Harsh Plateau
Land
: Add . Harsh Plateau deals 1 damage to you.
Daybound (If a player casts no spells during their own turn, it becomes night next turn.)
--------------
Haunted Tarn
Land
: Add or .
Nightbound (If a player casts at least two spells during their own turn, it becomes day next turn.)

Chaotic Laboratory/moweda
Very innovative. This penalty was never seen in canon lands, though similar to Jack-in-the-Mox and Gem Bazaar.
I'd give it ":Add ." to avoid a random check when which color don't matter.
It can be ignorable when you playing paper game, but it is needed in Arena.
Arena would be required to a special procession to forbid the cancel of the ability, or you can repeat the random until you get favorable mana.
It is a choice from two possible results but it is not a coin flip, so it will confuse some casual users.

Serene River/emberfire17
Unlike lands you mentioned, your one assures you to produce first mana for each color. It has something new but it is in a range of tap-in lands.
And also, this restriction has a loophole.
I assume this is a one of a cycle because dual lands are almost always a part of a cycle.
Then, you can have Serene River and 12 other white lands of the cycle and 12 other blue lands of the cycle to avoid this penalty.
You needed to give it one or more basic land types.

Pearlwater Garrison/ZephyrPhantom
Though this restriction is not yet seen in canon, it is a variant of tribal land.
And I doubt that its restriction brings a new feeling to game play.
I guess people would use this card mainly in a merfolk and soldier tribal deck. Then the most of times you need blue mana is that you have a merfolk in your hand, and it is same for white and a soldier. Maybe sometimes you keep a creature in your hand to activate some abilities or prepare blue mana for a counter spell in your hand but the more times you met this kind of situation, the more you would get to feel you want to change it with another dual land.
If there are many soldiers and merfolks whose main business is staying in your hand like Sky Husser, it might work well in some decks.

Harsh Plateau+Haunted Tarn/Flo00
Very interesting. Though constant damage is severe to use, aggro deck mixed with clock permission might use it well.
You can turn it any time if you want but sometimes it results you a tempo loss. This is a good restriction.
I love this mechanism for it is very flavorful.
Say high tide, haunted, nocturnal creature, faerie's party, ... and more. There're many reasons why a land turns its face when the night came.

Remote Floodplains, Unreachable Marshes, Impassable Pits, Distant Cliffs, Lonely Glades/vizionarius
At first, I misrecognized it as "If you don't, it etb tapped". Indeed, I didn't think this penalty. But I feel this is too risky to use.
And the most of time, it consumes an attacker or blocker. For aggro, it is unpleasable to tap a non-sick creature. And against aggro, reducing a blocker is also not favorable.
Some decks which have many creatures and don't care much about combat, such as Soul Sisters and Loop Junction might utilize it.
But even these decks would avoid it because sometimes it causes you cannot put it into play unless you're using kind of Orithopter.
I like all of your lands keep the distant flavor.


The winner is Flo00.
Both Flo00 and moweda were impressively innovative, but Flo00's one is more flavorful and doesn't have a problem of playability.
The runner up is moweda.

Can go right into the next kamigawa set.
