Chrome Mox plus Colorless

[Taysby]

does {chrome mox} exile say {ugin, the spirit dragon} create <>?

[InfinitiveDivinity]

No colorless is not a color, and therefore cannot be chosen


Which is also why chrome mox says "choose a nonartifact card..." to prevent this confusion

The rulings for it also say, chrome mox cannot be used to tap for colorless

So, exile Ugin and durdle?

[Kaylesh]

Exile Ugin or Emmy, it won't do anything.
