Hello! Yet another idea.
Well, who knows? Maybe you are tired of your Sleep Talk rolls ending in Teleport, Splash, or Growl. Maybe you are planning on using Last Resort someday, but you can't 'cause your Pokemon knows Explosion or Healing Wish. There's also the possibility that you never do double battles and are tired of seeing Helping Hand in your Pokemon.
Well, I'd say it would be fair to have a Move Deleter.
Maybe it could work like the Daycare except a bit cheaper. With a limit on how many moves you can delete of course and with a rule that says that your Pokemon can't have a move deleted if it only has 4 moves or less. Oh! And Definitely, the trainer should keep a list of the moves that have been deleted from that Pokemon in the stats page.
Anyone else thinks this is useful?
