Well then, raikous skill says:

Increases own damage against Demonic enemies for 3 turns. Increases own damage against enemy servants with Earth or Sky Attributes for 3 turns. (This excludes Demi-Servants and Pseudo-Servants.)

She deals damage against demonic enemies, and earth and sky attribute enemies, earth and sky attribute enemies are all enemies that have the attribute of earth and sky, see the attribute page for that. The trait Earth or Sky is a literal mix of earth and sky attribute servants and none of them have different attributes, Gilgamesh caster and Mecha Eli are neither of the Attribute Arth or Sky nor do they have the trait or are listed on this page.
