With the Poke Flute and Fuchsia accessible I got up to some shenanigans.
Duped some items don't worry, the Rare Candies will only be used to bring those Lv 7s up to speed and went on a bit of a catching spree. Noticed my Mew had a Special of 74 so I bagged an Articuno using the Ditto trick. Also evolved some Pokemon and filled out the party with a Primeape.

The funny thing is that with gen 7 they introduced an Ultra Ball. Had to be renamed to Beast Ball in the english games.
