hopefully that all made sense! I don't mind using showdown, but I just want the ability to have my pokemon learn whatever moves they can for story purposes and writing interesting battles/appeals for fun, if that's makes sense

Good questions. When I said that you didn't have to follow the events that happen in a showdown battle when you are IC dramatizing it, I was NOT talking about letting your Pokemon use moves that it couldn't have otherwise learned. I just meant that if you used tackle the whole time, you don't have to do so in the IC dramatization. 

So short answer is "no". If a Pokemon can't use a move in Showdown, they also can't use that move in IC battles. 

However, once a Pokemon learns a move, they never forget it. In other words, while you can only use four moves in a showdown battle, you may continue to use any previously learned moved for IC purposes. 

Also, TMs, Move Tutors, and Breeding will all come into play in this RP. I will control these events however (or at least set up the conditions by which you can encounter them on your own).
