This is a dumb gimmick cube that I've thrown together where the only converted mana costs that are allowed are 2, 3, and 7. It's called Afternoon Delight because 2:37pm is in the middle of the afternoon.

The one specific house rule that you'll need to keep in mind is that all Instants and Sorceries are Arcane. This change was made because Splice onto [X] is a fun "build your own kicker" effect.
