This set aims to bring together all the fun artifact synergies from artifact-themed sets like Mirrodin and Kaladesh.
The cube aims to offer a variety of potential game plans, from aggro to control to even combo decks. The “planted” archetypes (as suggested by the signpost uncommons) for each color pair are as follows, but there should be plenty of other options to draft beyond these:
WU Affinity/Blink
WB Revolt
WR Welder/Reanimator
WG Tokens/Midrange
UB Control (aka strix tribal)
UR Artifact Value
UG Investigate/non-creature tokens
BR Sacrifice
BG Sacrifice
RG Treasure
