I never really cared for the Nuggets, I always have way too much money to spend on the pokémon games. And in RSE it's also so easy to get money by just battling that lady and the rich kid at Route 104 over and over again while holding amulet coin and stealing the nuggets that their Linoones hold with Thief or Covet, $19200 per battle cashing in :P. PP ups are really useful, I got a few of those.
Master balls are the cheapest thing ever invented. It's more fun catching everything with balls that can fail. 'caught Latios in the wild without master ball ftw'
