This is a collection of cards that benefit from playing a color you don't necessarily need to play it.
This does not count artifacts with colored activation costs. But it does count artifacts with two abilities that use different colors (e.g. Wand of the Elements). No five-color costs or domain/converge things. Also no hybrid costs on monocolors of one of those colors.
In the maybeboard are a few cards that play on something not really supported by the cube (e.g. white Auras).
