is it possible to return an enchantment creature card (like Baleful Eidolon) with Dawn to Dusk from the graveyard? I'm not sure if an enchantment creature is a special type or just two types (enchantment and creature).
I appreciate your help!
Yes, you can. Baleful Eidolon is an enchantment and a creature. Anything which targets or affects either of these permanent types can target or affect it.
