This cubes idea is that there are no creature spells. Yes there are spells that make tokens but they aren't creature spells and it would be super lame to play with out any creatures.

I am aiming to 540 card cube. Usually I add cards when new sets are released or if I figure out new archetypes. I subtract cards when I or my friends think something is too stupid or too weak.

Example archetypes:

Boros: Equipments
Dimir: Zombies
Izzet: Spells Matter
Selesnya: Tokens
Azorius: Artifacts Matter
Gruul: Lands Matter
Orzhov: Aristocrats
Simic: Graveyard Matters
Rakdos: Discard/Madness
Golgari: ???

The color combinations are flexible and have cards to different archetypes so that's why these are just examples.

One archetype I'd be exited to add if it had enough support would be Artifact Reanimator with cards like Refurbish or Trash for Treasure. Sadly there is only handful of those animation effects and there aren't many artifacts you would even like to reanimate. That plan has to wait, but I will be excitingly waiting for more cards.
