LOTS OF ARTIFACTS. Just something whipped up for fun in anticipation of Kaladesh. I made this with no consideration to draft archetypes, just looking at trends which evolved as the cards amassed. However, this is a loose understanding of the draft archetypes in this cube:

W/U: Metalcraft (clues/equipment serve as sitting artifacts to turn on metalcraft)
U/B: Affinity (artifacts double as value and fodder)
B/R: Sacrifice Artifacts
R/G: Artifact Hate
G/W: Go Wide Tokens
W/B: Value/Graveyard Recursion
B/G: Graveyard-Matters Artifacts (self-mill and recursion)
G/U: Proliferate (charge counters)
U/R: Spells-Matter Artifacts
R/W: Equipment Matters
