This cube is designed for 2-player draft (Pancake Draft). The goal of the cube is to have interactive games. Pure combo decks are not supported.

Blue: counters, card draw, utility creatures, blink
Black: removal, discard, reanimation, sacrifice
Red: aggro, removal, midrange, sacrifice
Green: ramp, midrange, high-end, instant creatures
