I don't think I have exact numbers since I sometimes just think of one and add it in with no real planning but..
I've got 2 for Chapter 1 and 2 more for Chapter 2 at least.
Plus a MAJOR one I'm setting up in Chapter 5!
There was that Swalot suggestion for Chapter 3 and I think I finally have an idea for Gardevoir thanks to another suggestion.
I will admit, all the stuff I'm setting up might make this update take longer than the others.
