What if I had a Pokemon Gym

Recently I've been watching a lot of seen "What if I was a Pokemon Gym leader?" and as an aspiring writer, I decided to throw my hat into the ring. Once I started making a gym I thought about making a gym for every type. I do not have a favorite type per se, but the more I thought about it the more I wanted to make a gym for every type, so instead of just making on gym with my favorite type, I'm going to a gym for each type. This is my first fanfic creation so please give constructive criticism. Disclaimer: I am not an expert on the pokemon moves or competitive battles, I am basing my team only around typing and which ones I like better.
