This cube was originally created by CubeCobra user 'supachai' (or 'schai' on reddit), but I can no longer find it on their profile.

Supachai's description: "It's a heavily curated (3-4)/2/1/1, with really janky commons and uncommons cut down. Some rares also cut due to being not great in cube, such as Emrakul... ain't no one getting to 15 mana. 450 is the chosen size since that's what my box fits :)"
