Got this notion from Levia-Dragon - Daedalus' second ruling:
You can't send a face-down "Umi" or "A Legendary Ocean" to activate "Levia-Dragon Daedalus"' effect.
I've actually set a field spell card before just to act as bait for my opponents spell/trap removal but I've always been unclear as to where exactly a face-down Field Spell Card is supposed to go. Since it's an indeteminate card face-down, does it go into your five-card S/T Zone then into your Field Spell Zone when flipped? Or does it actually have to be set in the Field Spell Zone?
