My 540 unpowered cube!

Construction notes:

+Hybrid 1CMC 2/1 Aggro creatures AND functionally identical hybrid cards break guild slots and go into a Mono-color

+No more than 5 Planeswalkers per Mono-Color and Colorless section

+Guilds - No more than 2 removal spells and 2 Planeswalkers

+Ten slots free for cards with more than three colors, and no more than 2 of the same shard/wedge

+Unique > Redundant as a rule. Ideally no functionally identical cards in a given color/mana value outside of necessary archetype or interaction redundancy
