Dream Halls and Eldrazi

[kilukru]

Since Eldrazi are colorless, can you remove a colorless card from your hand to play an Eldrazi?

Edit : Ok found my answer : 105.4. [...] “Multicolored” is not a color. Neither is “colorless.”

Sorry for that.

Since colorless isn't a color, you can't share it. So: no.

[Fatestitcher]

also, you don't remove. You discard.

Yeah, they were pretty careful to avoid any Dream Halls, Tinker, Natural Order, etc. shenanigans with the Eldrazi guys.
