In limited mode drafting, can you include a signature spell if you only have one of its two required domains?

Ruling: You need both domains to include a signature spell while drafting in limited mode.

Nuances:

• This applies even if you are drafting colors that include one of the required domains (e.g., drafting red-blue-green does not allow you to include Dragon's Rage, which requires the orange domain in addition to red)
