Expanded Gyms and E4 Ideas

gym leaders and thought about a way to make the themes og gyms more interesting:

Dual Type - Uses 2 types and ace has both, for example, a ghost and fire type Gym lederhosen, has a gangar, camerupt and a ceruledge as the ace

Weather - Team is a weather team rather than a type with ace being weather setter

Terrain - Same as weather but with terrain

Stats - All the pokemon excell in one stat, for example, Speed with weavile, ninjask, ect

Shinny - Uses a well balanced team of good shinnies

These are just the ideas I had, someone probably talked about this already but I wanted to talk about this because it came into my mind.
