LF: nicknameable Xerneas, Articuno, Moltres FT: legendaries, leftovers, shinies

[6]I have:

3x leftovers

Shinies: 4IV Ekans, 4IV Amaura, trophy Audino. I might have some other shinies I can part with, if I don't get takers.

Pokebank Legendaries (from the GTS): Terrakion, Cresselia, Lugia, Rayquaza

Unowns: several letters

I am looking for XY legendaries that can be nicknamed as follows:

Moltres - Fawkes

Articuno - Yako

Xerneas - Swala

Please let me know what you think is fair! I have no idea what these are worth.
