Hall of Gemstone
World Enchantment
At the beginning of each player's upkeep, that player chooses a color. Until end of turn, lands tapped for mana produce mana of the chosen color instead of any other color.

note that the list hasn't been implemented yet. That specific part does hit Magus, Balance and Cataclysm but doesn't hit Razia's Purification, Balancing Act nor Pox. I can add in an additional option for permanents, Pox has unique wording so will have to be manually added.
This is what I have so far.
Mass Land Denial:
"sacrifice ... lands"
"each player sacrifices ... lands"
"return ... lands to their owner's hand"
Exception: If the above ... has "two" or "three" in it for any of them.
Note the requirement for the word land to be plural.
"lands don't untap"
"Players can't play lands"
Exception: If the card is instant or sorcery.
"each player ... chooses ... land(s) ... sacrifices the rest."
"return all lands to their owners' hands"
All instances of the word "land" dictated as a requirement in the strings above can be swapped for "permanent".
"Whenever a player .... that player returns a land they control to its owner's hand."
"lands are (land subtype)."
All instances of the word land dictated as a requirement in all the strings above can be swapped with "nonbasic land", "Plains", "Forest", "Island", "Mountain" or "Swamp".
All instances of the word "sacrifice" can be swapped for "destroy" or "exile".
All instaces of the word "player" can be swapped for "opponent".
A global expection for all Mass Land Denial is made if "nonland" is ever in the textbox.
Individual cards bypass exceptions.
Individual cards: Desolation, Equipoise, Hall of Gemstone, Mana Vortex, Mist of Stagnation, Parallax Tide, Pox, Quicksilver Fountain, Sands of Time, Smokestack, Storm Cauldron, Tangle Wire, Temporal Distortion, Thoughts of Ruin, Words of Wind, World Queller

Anything anyone thinks is missing with this?
Tutor:
"Search your library for ... card"
Exception: Tutors that, within the above string, have the words basic, Plains, Forest, Island, Mountain or Swamp.
This should catch instances of multiple cards being tutored.
Individual cards: Demonic Consultation, Divining Witch, Tunnel Vision
Mass Land Denial:
"Destroy/Exile ... lands"
"Each player/opponent sacrifices ... lands"
"Return ... lands to their owner's hand"
Exception: If the above ... is "two" or "three" for any of them.
Note the requirement for the word land to be plural.
"Each player/opponent ... chooses ... land(s) ... sacrifices/destroys/exiles the rest."
"Return all lands/permanents to their owners' hands."
"Whenever a player .... that player returns a land they control to its owner's hand."
"lands don't untap"
"Players can't play lands"
Exception: If the card is instant or sorcery.
All instances of the word land dictated as a requirement in these strings can be swapped with "nonbasic land", "Plains", "Forest", "Island", "Mountain" or "Swamp".
All instances of the word land/lands must not be nonland.
Individual cards: Blood Moon, Desolation, Equipoise, Hall of Gemstone, Mana Vortex, Mist of Stagnation, Parallax Tide, Sands of Time, Storm Cauldron, Tangle Wire, Temporal Distortion, Thoughts of Ruin
edit: quietly adds "Hall of Gemstones" as a synonym to Hall of Gemstone

SufferFromEDHD I don't run Hall of Gemstone because it locks the entire table out of interaction, including ourselves, when someone tries to win on their turn.

- You'll add , since Wastes is a mana producing land, but Overgrowth is not.
- Same situation, Island will add , but Market Festival will add two mana of any combination of colors.
- You'll add plus two mana of any combination of colors. Island added , and Mirari's Wake adds one of any color it produced, which doesn't leave many options. It cannot add one that Market Festival added, regardless of the Hall of Gemstone.
- Both Market Festival and Mirari's Wake have mana abilities (which trigger from other mana abilities). Since mana abilities resolve immediately and do not use the stack, Weaver of Harmony cannot target them. Weaver of Harmony can target the trigger from Hall of Gemstone (assuming you control it), which would let you choose a second color. When a land is tapped during that turn, there will be two replacement effects, so the land's controller will get to choose the order in which the effects apply and end up with either of those two colors.

I have a Hall of Gemstone in play. At the beginning of turn I declare White.
-
I tap a Wastes with a Overgrowth on it for mana. What do I add?
-
I have a Island with Market Festival and tap for mana, do I add XX (x being my choice of colors) or ?
-
I have a Mirari's Wake in play also. With that Island taped for mana, do I get , XX or do I get XXX?
-
I have Weaver of Harmony in play. Does his ability work on Market Festival? If so, how does that work with the Hall of Gemstone and Mirari's Wake in play?
RiotRunner789 on Favorite EDH Cards

My favorite card is Grave Pact but that isn't quite niche. I don't seem to have as many oddball fun cards that I tend to play but there are a few oddball or less played ones at least.
Black: Koskun Falls is a favorite of mine. I prefer decks that do not attack, so the tapping is not a big downside. Tainted Remedy because it makes opponent's creatures with lifelink funny. Gift of Doom which doesn't use the stack when morphing which has come in handy more than once. Pestilence is one of my favorite black board wipes which typically is on my board with an indestructible creature. Dystopia since at least someone is playing Selesnya.
White: Peacekeeper because no means no. Aura of Silence use to be more niche but has seen some prominent reprints. Solid removal with a tax effect has tripped up more than one opponent. Mandate of Peace is a great fog and a counter spell in some situations. Underplayed.
Green: Hall of Gemstone for any monogreen deck. Had a blue player try to win on my endstep and about 5 minutes into their combo, I asked where there blue mana was coming from.
Orzhov: Batwing Brume has killed a few Kranko players for me and saved me several times.
Colorless: Null Brooch is just Isochron Scepter with Negate already attached. Arena of the Ancients is great for when my commander doesn't need to tap, or attack, or is played after this and has vigilance. Great card no one expects.
Red: Apocalypse or Jokulhaups for the hard reset. Stranglehold because blue players are the worst and tutoring takes too long.
Blue: Mana Vortex for the slow decent into hell.
