Based on Ryan Saxe's combat cube: https://www.cubecobra.com/cube/list/combat

This cube is meant to have fast and intense gameplay. My goal was to make the most engaging, skill-intensive, gameplay experience, focused on the combat step, while maintaining a broad set of strategies in each color combination. For example, Gruul can be a Temur Battlerage combo deck, but it can also be any deck from hyperaggro-midrange with themes like Energy, +1/+1 counters, and direct damage. This is possible thanks to overlap. Energy creates +1/+1 counters. It also has cards like Bristling Hydra that are great in any deck, but especially good in the Temur Battlerage deck! I also attempted to seed enough flash, lifelink, first strike, and vigilance in order to reduce games where players just race like two ships passing in the night. My hope is that this makes blocking more of a thing, and keeps combat difficult and full of bluffs.

Finally, I built this cube with a couple of restrictions:

1.) Must be 360. I think it's important for a cube like this to have all cards drafted. It needs to be feasible to play around cards as well as bluff them!

2.) No shuffle effects. Insures quick pace of play and focus on the combat step has no sideline
distractions.

3.) The only way to gain card advantage is through Combat (e.g. Ophidian is allowed, Mulldrifter is not). This is a soft restriction. I think it's okay to break it for gold cards, as well as A + B combos (e.g. Zealous Conscripts + Sac Outlet as a build-your-own Flametongue Kavu).
