I HAVE BEEN SUMMONED
Sketch tutor is fun but you'll probably also need to consider adding a double battle to make using sketch easier at that point. Networking blocks blatantly illegal things from what you told me so it wouldn't even be that disastrous.
Considering you're in Essentials though, if you don't mind a coding nightmare you could always just have a set of NPCs for every type that just have global move tutors for every move in the game. Way easier than sketch for the player.
