Moves teaching simplification

[Inces]

In current, classic approach to move teaching system, it is quite annoying to make changes to pokemon moveset, which discourages players to experiment with various moves in PVP.

For example : If I want to swap Flamethrower with Trick to Togekiss I have to travel to tutor in Johto. To revert that change I have to go get and buy flamethrower TM again. 

 

Suggested sollution :

Metadata of already taught moves stored for every pokemon. NPC that allows to access this metadata and relearn stored moves freely, or for symbolic price. 

This will also add another quality to pokemon economy - amount of moves stored in its memory.

I would also like to suggest analogic sollution for already trained EVs
