need halp, /vp/

I was hatching Brave HA Ralts for a Trick Room Gallade, and ended up hatching a shiny with four perfect IV's.

Problem is, it's a female, so I clearly am in a pickle regarding what exactly to do with it, since it has a +Attack nature but Gardevoir can't do shit with physical.

I just don't want to see a more than decent shiny Pokémon just sit in the box.
