Ability to turn moves back into books
For instance, lets say I have a smiter that I don't use anymore thats like E+ that I taught poison leaves a long time ago when I didn't understand the game as well. I also have an S flight that I want to teach poison leaves. With a function like this I could turn the poison leaves on my unused smiter into a book that I can teach to flight where it would be much more useful.
Certainly, there should be limitations on this. Of course a cost, maybe a small amount of EoW and silver. Maybe a limit on what moves it can be done to. And there would also have to be a cool down or limit on how many times it can be done to prevent people from just switching moves and exploiting the mechanic for competitive gain.
Tell me what you guys think. I think it would be really helpful. After all it does take a lot to earn those books:3.
