At a GlanceThis cube has a unique rule.
Each player controls two decks. One deck contains lands, the other contains nonlands. Whenever a player draws a card, they may choose which of their decks to draw from.
Players must draw their opening hands face down, but may look at it before choosing to mulligan. I.e. you choose the distribution of your opening hand before knowing what you draw.
If a card or effect would interact with a library/deck, the controller of that effect chooses which library to affect. Ex; Player A casts Thought Scour. They may target their own land library, their own nonland library, their opponent's land library, or their opponent's nonland library.
A Temple of Silence may scry either library.
A Brainstorm may draw cards from either library, and may put back cards onto any library.
If a card would be put in to a library, put it in the appropriate one.
Major Philosophy Decisions:
No Wraths. You shouldn't need to play catch up. Though you may find a few mana-intensive alternatives, like Pyrohemia.
No easy two-for-one's. No Skyclave Apparition or Ravenous Chupacabra.
No easy card advantage. After all, if you're drawing all gas, you shouldn't need it. There may be a few mana-inefficient ones, like Prying Eyes.
No planeswalkers, because they dumb.
Cheat on mana, not cards. Phyrexian mana, rituals, dorks, and put into play effects are all fair game. Spend it wisely, because it all costs card advantage.
