I am in the same boat as you in that regard. I can beat most of my friends in Smash, but if I played against someone who's into competitive, I'd totally get killed. However, I've been breeding plenty of 4-5IV Pokemon, some with hidden abilities, so I have more than 10 options for Mega Evolutions and a few other competitive options now.
Also, I had the idea that you could have been female at first because of the word Sapphire in your name, but I didn't want to assume you were female until I could confirm.
