I am taking a Grixis cube and am cutting out black to make a 4 player cube. A 3 color cube was still going to be too many archetypes for 4 people, so no one would have to "fight" over cards in the draft.

With just two colors and colorless, this means 2 mono color decks, 1 guild deck, and 1 or 2 possible artifact decks means there's 5 archetypes to 4 players, like 10 archetypes for 8 players in a normal draft.

We don't want such a simple draft of "find your lane" that has no competition over cards or archetypes. This way, 4 people will be competing over the 2 colors, possibly one person likely playing a mono-colored deck, and colorless being a support theme instead of a 3rd full color. Colorless will enable archetypes, not be an archetype all to itself.

It is cut down to 270 cards for either 4 player sealed or 4 person draft.

Total list of possible archetypes below:
U Tempo, control
R aggro/prowess, Big R
UR control
UR artifacts tokens
Total list TBD.
