Rule 707.10g

If an effect creates a copy of a double-faced permanent spell, the copy is also a double-faced permanent spell that has both a front face and a back face. The characteristics of its front and back face are determined by the copiable values of the same face of the spell it is a copy of, as modified by any other copy effects. If the spell it is a copy of has its back face up, the copy is created with its back face up. The token that’s put onto the battlefield as that spell resolves is a double-faced token.
