This is the Companion Cube.
It began its life in a shoebox, filled exclusively with cards I opened at draft//sealed//traded for.

At present, it is a mostly-Legacy legal cube meant for drafting with up to 7 friends.

The 10 Ikoria Companions are the loudest cycles in the list. At present, I would say G/W and R/W are the most difficult to companion in the base color pairs, and G/U is at something of a tempo disadvantage if companioning Keruga.
Otherwise, there are general archetypes to pursue.
Mono color aims include aggressively slanted colors in the Naya, Graveyard shenanigans centered in black, control in Esper/Grixis. green ramps unsurprisingly well.

There are no game-ending two-card combos at present, some cuts have been made to the top and bottom ends of the power level for gameplay and structure reasons.
