This cube isn't really powered and the archetypes in it are the following :

• Threshold (GW) -Equipment (RW)
• Inspired (UB) - Sacrifice (GB)
• Storm (UR) - Artifact (U)
• Heroic (RB) - Merfolk (UG)
  Some help for your first draft of it :
  Cycling help for threshold, auras help for heroic and vehicle helps for inspired.

There is also one card that defines an archetype but if you don't have it nothing happens let's say it's the creator's special touch thanks for reading and I hope you'll enjoy the gameplay.
