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:

• Cards are drafted in 2 packs of 10 cards
• The minimum deck size is reduced from 40 cards to 15 cards
• Players do not lose the game if they would draw a card from an empty library

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.
