A mini-cube, where most cards in the deck care about the graveyard in some way. While there are no color-pair archetypes, the cube features a central theme for each color, and it's up to you how you want to combine the different colors:
White - Reanimator
Blue - Mill (Any player)
Black - Graveyard consumption (Delve, etc.)
Red - Discard
Green - Graveyard accumulation
The cube is also rarity-balanced: We have 12 rares, 36 uncommons, and 132 commons. Apart from the colors, the colorless artifacts also generally help with graveyard effects. Lastly, the special lands in the cube are all Deserts. There isn't much in the way of color-splashing, but there are some cards that offer treasures or mana filtering.
It's been a while since I even touched this, but the sets that have been added have made me want to update. I believe the sets were:
Kamigawa: Neon Dynasty
Innistrad: Crimson Vow
(Partial) Innistrad: Midnight Hunt
I had put some cards from Midnight Hunt into the cube, but I was half-hearted in doing so. Now, however, I think I can come back to this cube for maybe half a year or so, and consider graveyard-interacting cards. Hopefully, considering the cube's niche, we won't be looking at a lot.
For now, we look at cards that I'm interested in, but I won't be explaining because I think it's going to take too long

There are no promises on how much we can put in the cube, but having a short-list is probably good for my sanity. Let's come back to these at one point during the year and see how many actually get in!
EDIT:
There were some changes to the cube that wasn't listed here, but was listed in a local file of mine. Here are the cards (probably):
Lunarch Veteran
Mourning Patrol
Drogskol Infantry
Cenn's Enlistment
Search Party Captain
Ghost of Ramirez DePietro

I'll maybe replace the whole cube if this list is too different from what I have on the other set, but we'll have to see.
