i'm unfortunately too busy w/ school to do so, but i would definitely recommend hopping on pokemon showdown and playing matches on that sim. it will accelerate your skill a lot more quickly than a 3ds team will, and it's infinitely easier to make tweaks and changes required to get better. smogon has some really awesome resources too.
Hello. I noticed your well versed in Competitive Battling. I am new to competitive battling and was wondering if you would tutor me. I don't have a 3DS yet, however I hope to soon.
