You mean the XYZ field spell? Dunno what that has to do with this card, but I'm very sure we'll never going to get Union Hangar.
Mainly because Union Hangar is one of the field spells easily abused by Ancient Fairy Dragon, and I don't think Konami will want to hit AFD here in a game where Luna actually exist, so we're simply not going to get Union Hangar instead.
