Since you already have Sniper Shot from Dark Amaterasu, shouldn't you be rushing for Joan instead?

SSR Amon + Dark Amaterasu + Andromeda with Joan's Trial by Jury would get you -45% Def, -40% Atk, Black Propaganda and heals. It's not the perfect team, but when combined with Beelz, you shouldn't have any issues.

Your other teams... well, you could probably bring Dark Amaterasu in all of them and solve a lot of problems. But overall, rather than trying to get multiple decent teams, you're probably better off just focusing on your Dark team.
