Oh, I don't do any of the IV/EV things either, except for this one time that I was breeding 5/6IV Eevees for Sylveon and Umbreon. I don't know why I did it, I'm not going competitive, but it somehow just feel more complete having the "perfect" pokemon, you know? I was the same with Fairy. First look was just modifications to a bunch of existing Pokemon that are now labeled Fairy. After a closer look, there are actually a few good Fairy ones out there. Ralts is one, which would probably be one my top two along with Abra (if going Psychic). And, of course Sylveon (#1 if going Fairy though not till late game I think)!
