This is a proxy copy of @Andymangold's Degenerate Microcube. The only change I've made is to swap out Lotus Petal for Black Lotus, because when else could I play with Black Lotus?! Check out his Primer for the full story on a truly unique cube (including deck archetypes), but here is his summary:
The Degenerate Micro Cube is a 160 card cube that uses draft, deckbuilding, and gameplay rules adapted from Max Hero’s 15 Card Singularity format:
Under these conditions, the Degenerate Micro Cube pursues many of Magic’s most broken and degenerate strategies. The present macro-archetypes are better described as combo, stax/prison, and control, rather than the more prevalent aggro, midrange, and control.
