This cube is a custom limited environment that only includes cards from Magic Origins Standard sets (M15, Dragons of Tarkir, Fate Reforged, Khans of Tarkir, and Magic Origins). While it does not support the Standard Metagame Decks of that era, it does support the three-color guilds of Tarkir and all 10 two-color pairings.

It was originally built in 2017, and had upgrades in 2018, 2019, 2021 and 2023. Previous versions were on Cube Tutor until it went dark. The previous versions all had a color or guild power imbalance.
