All cards must be cmc 1 and available in a modern or m15 frame. The mana cost itself must be exactly 1 pip (additional/alternate costs and activated abilities are fine). The card must be one Magic card (no split cards, MDFCs, adventures, aftermaths, etc.).
The only exceptions to the above are a few fixing lands included to alleviate color screw.

• No color hosing or overly narrow hate cards.

• Cards are categorized into the color that wants them.

• Avoiding DFCs for ease of drafting.

Because there isn't really a "curve" in the usual sense, it's harder to fit decks as neatly into traditional archetypes like aggro, midrange, and control. General principles still apply (red is more proactive, blue is more reactive, etc), but every deck is going to be playing spells very quickly.
