General Archetype suggestions for a Lands Matter cube?

This is my first time making a cube, and I like the idea of making every archetype related to Lands. I've made a ton of janky lands decks in EDH, like a [[Urborg, Tomb of Yawgmoth]] secret commander deck with cards like [[Crusading Knight]], legendary lands copying deck with [[Cadric, Soul Kindler]], and land bounce deck with [[Patron of the Moon]]. I'd would love to curate a limited environment which uses some of these cards but am having trouble coming up with what to do for some of the archetypes.

Right now I like the idea of Gruul as Land Discard theme utilising cards like [[Borborygmos Enraged]], Golgari as a self mill lands in graveyard matters using [[Spider Spawning]], Boros as land sacrifice and mass land recursion with [[Second Sunrise]] and [[Mana Seism]] type cards. I also think boros could house the lands discard theme with a [[Land Tax]] type cards being used to fill up hands to be able to discard better. A creature land aggro deck could definitely be fun as well as a land aura untapping deck maybe.

There's definitely some more difficult colour pairs to work with such as Orzhov but I wanna see the idea through. Any advice or suggestions would be much appreciated!!
