A cube designed to permit drafting current and historic modern archetypes including yawgmoth, titian/scapeshift, cascade and dredge. Every card in the cube was at one time modern legal, and I've tried to include some representation for all of the top modern decks (I can't make tron work for obvious reasons and i decided against mill because I dislike it)

W/U = Control or artifacts
U/B = dredge/graveyard (you may want to splash green for this one)
B/R = Tempo/Scam
R/G = Domain/land combos
G/W = Enchantress
W/B = Reanimator
U/R = Spells/Storm
B/G = Creature combo
R/W = Humans/death and taxes
G/U = Cascade

Also keep an eye out for Hamertime/Equipments in white, creativity in red, and 5 color omnath/bring to light. Good luck and have fun.
