5: The Move Tutors and Move Deleters
If you’ve ever played Pokémon and lovingly trade-linked all your previous generation monsters to a new game to exploit their latest move-sets, then you’ve certainly had a little help from these guys. When I first played Ruby all those years ago and found out I could now actually delete HM moves, I almost shed tears of joy– true story. Although they’re often scattered across disparate towns and locations, it’s an undeniable fact that the Move Tutor/Deleter teams have offered an incredible service in all corners of the Pokéglobe, usually for free too! Heart Gold and Soul Silver even put them in the same house for you, making them a one-stop shop for all things move related.
