360 Card Singleton Peasant+ Eternal Cube
Paper and Digital (MTGO and MTGA) Legality
Rarity Breaks:
Mana Confluence - Mana Confluence is nearly a functional reprint of City of Brass which was printed at uncommon in Arabian Nights. I would be shocked if the slight difference in wording would ever come up a single time in a thousand games.
Enemy Color Snarl Lands - The five allied Snarl Lands are uncommons on MTGA so I'm glad to complete the cycle in my Cube. I'd love to see more dual lands for Peasant Cubes which can enter the battlefield untapped.
All basic lands are snow-covered.
