Whenever its control, tempo, reanimator, flicker, aggro, or artifacts, this cube is all about the best tri-color grixis. All cards and lands for the cube are entirely in the blue//black//red color scheme and provide a unique take on drafting without two other colors in magic. The main themes you can try to follow are:

Control
Reanimator
Flicker
Tempo Aggro
Artifacts

But feel free to build whatever! Every card is playable, and value piles are easily accepted!
