This is my most recent cube. It's a 2hg draft cube and the list is pretty involved.

Most of the multi-colored cards, like in modern day sets, are signposts for their colors. However, not all two or three colored cards do the main thing the colors do. (Either due to power level or because I like the card)

Some color pairs have multiple identities with broad synergies, some color pairs have only one, but more focused.

Selesnya is mostly comprised of tokens and +1/+1 counter synergies. You can go wide, go tall, or both.

Gruul's main identity is storm. Granted, you and your partner won't get the storm count to 14 and Tendrils the opposing team for 30 damage. Storm in this cube accrues value to eventually win. In addition, this is one of the two main colors for cascade.

Orzhov's identity is aristocrats. Sacrifice your creatures for value, or to win.

Boros is artifact (mostly creatures). Boros is also the most "agressive" color combination, but in context that just means a slightly lower to the ground mid range deck. (Future updates will probably include boros as an actual aggro deck. We shall see)

Golgari decks want creatures in the graveyard. Then you slam big creatures to take advantage of your big graveyard.

Izzet identity is instants/sorceries with some room for artifacts as well.
Cards that trigger when you cast a 'Non-creature spell' bridge the gap a little bit if you have artifacts in your spells deck

Rakdos identity is reanimator. Put the big creatures into your graveyard and bring them right back to party!

Dimir does a lot with the graveyard. It might reanimate big creatures, or you might copy them while they stay in the grave.

Simic's identity is ramp. The really cool thing about Simic in this cube is there are many options to ramp your partner as well if you want. In addition, Simic is one of the two main colors for cascade.

Azorius's identity is artifacts (creatures or non-creatures) Accrue value by stacking a ton of clues.

With this being a 2hg cube, there are cards that affect the game in a different way than it would in 1v1 (there's a few cards that deal damage to each opponent, but nothing busted like fiery confluence lol.) You can have a deck that synergizes with itself and/or with your partner's deck.

Draft notes: meant to be played with 4 teams, but can play with up to 6 teams (2 pods of 3 teams.) 4 packs of 16 cards per team. Rules are the same as Battlebond draft. Two picks per team instead of 1, first mulligan is free, first team does not draw on the first turn. Each creature attacks any opponent, but each team member can block for the other. Both players in a team share a life total, so if one player takes five damage then the team goes from thirty life to twenty-five.

TLDR Good luck and have fun.
