Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
That'd be okay! Let me just think of a nickname for Landorus!
The Feebas is nicknamed Minerva and the Ralts is male and nicknamed Orpheus. I also have an un-nicknamed version of the Ralts if that is more to your liking.
I've ways wanted a shiny male gardevoir nicknamed "Tucker"... So unless the female has HP fire or something I'll be OK with the male with the aforementioned name.
It's a trainer shiny value, so I won't be able to rename him. That's a wonderful name choice though. If you're still down to trade, do you want the Ralts to be Orpheus or simply Ralts?
