This cube is meant to replicate an actual set so it's built with 6/3/1 split for commons, uncommons, and rare/mythic rares respectively. Has some multicolor but a strong mono-color bend to it. The maybeboard is for the "Basic Land Slot" that would be there in paper (same rules as drafting snow lands; you can't just take the land, you have to draft them). Sub-themes include energy and big mana. Draft archetypes are as follows:
White/Blue: Auras
Blue/Black: Mill
Black/Red: Demon Tribal
Red/Green: Sacrifice
Green/White: Equipment
White/Black: Lifegain
Blue/Red: Burn
Black/Green: Artifacts
Red/White: Combat Tricks
Green/Blue: Cheating costs
Each comes with a signpost uncommon legendary. Cube also has colorless support and is very creature-heavy.
