This is a cube based on current Standard as of Aetherdrift, including the following sets:
Dominaria United
The Brothers' War
Phyrexia: All Will Be One
March of the Machine
March of the Machine: The Aftermath
Wilds of Eldraine
The Lost Caverns of Ixalan
Murders at Karlov Manor
Outlaws of Thunder Junction
The Big Score
Bloomburrow
Duskmourn: House of Horror
Magic: The Gathering Foundations
Aetherdrift
I'll be doing a single big update for Duskmourn and Foundations at once, but for now I'm adding the duel lands from Duskmourn.
