The first cube I've tried putting together after years of playing the format. As cubes tend to do, this one started with a core of ~100 personal favorite cards from years of collecting, the rest filling in to construct a tolerable draft experience. Not all of those original hundred remain (RIP Degavolver) but they did a great job laying the foundations for color balance, power level, and overall themes.

Legality here is "Legacy", though the power level is markedly lower than what you might come to expect from a Legacy cube, with major emphasis on a fair/battlecruiser style of magic. This isn't to say that aggro and combo aren't supported, but there are much fewer cards that exclusively fit their styles and a lot more that are splashable; for example you can expect more cards like Scrapwork Mutt over Jackal Pup, and combos like Naru Meha + Saw in Half + Nondescript Creature over Kikki/Conscripts. Control was tuned appropriately, with sweepers being less "final" and more situational (think Extinction Event over Damnation) to allow the former archetypes room to breathe.

The cube is structured in a triangle-style; there are five wedges/shards that make up five actively supported themes, then each of those themes can be further broken down into more nuanced color-pair archetypes. Additionally, the pairs shared by triangles serve as a thematic bridge between the two. For example, the pair shared by Mardu (Aristocrats) and Esper (Artifacts) cares a lot about swarming the board with artifact tokens and using them as resources, either buffing them or sacrificing them to benefit cards like Retrofitter Foundry and Marionette Master.

Classic Artifact synergies abound. You're either swarming the board with tokens, making ginormous Karnstructs, playing Game Objects.dec with Academy Manufactor, or all of the above. Will give you access to the most stereotypical artifacts deck with the most "Artifact"-y payoffs, while will give you tools like Ruthless Technomancer to play Reanimator, and will allow you to swarm the board and grind out your opponent with cards like Fain the Broker.

Do you care if your creatures die? Me neither. This is another classic archetype featuring well-known staples. is the most typical Sacrifice deck, with effects like Mayhem Devil to take advantage of your things dying. , as mentioned above, leans into the idea of grinding your opponent out, while tries to blitz them with a swarm of smaller creatures that couldn't care less about winding up in the 'yard.

Creature tokens, and everything that entails. Makes 'em wide, makes e'm tall, and makes e'm just right. If you want to bully your opponent into submission by turn 4, exhaust them by cloning the same Wurm token five times, or just beat them down with Plants as all token decks should, the one thing that's for sure is that you won't be using real cards to do the deed.

It works, I promise.

This is definitely the most unconventional of the bunch. Your focus is primarily to play a few specific powerful cards, then copy and clone them to your heart's content. wants more of its Wurms, wants more of its instants, and wants more of its Everything Else. You haven't lived until you play a Myr Battlesphere and responded to the etb with a Mystic Reflection, and that's just the tip of the iceberg.

And we're back to the classics. For the uninitiated, the plan is simple: Take your deck, and PUSH it somewhere else. Ideally this will be your graveyard, but the battlefield works too. cares the most about dumping a critical mass off cards into your yard, while simply doesn't care if its cards get dumped in the first place; those will just get flashed back regardless. To round things out we finish where we started, with a deck that dumps big lads in the yard then drags them right back.

Shoutout to Cubecobra user @Archytas for writing an article on the philosophy of a triangle cube and inspiring this cube's design. Below illustrates the general distribution of colors and archetype overlap for this environment, as discussed in that same article. Here, a point pair references a color pair possessed by only one of the three-color themes while an overlap pair is one shared by two themes. Point pairs tend to embody the theme they are exclusive to an have the most buildarounds, while overlap pairs share support cards from two themes and tend to be more flexible in how they're built.

Beyond the prescriptive themes there are also the usual suspects ( Ramp, Aggro, x control, etc) with a lot of the hallmark powerhouses that support these archetypes, so people who want to draft something they're comfortable with are more than able to do so. The cube is still a work in progress as I'm constantly finding cards that need to come out (turns out Urza's Saga is pretty good) and cards that absolutely have to go in. Some kinks have to be worked out, but I'm happy with how far this cube has come in the months since its first iteration.
