>>27109352Best tip I've got so far; evolve
Rattata and Pidgey are numerous and evolve with, like, 25 and 12 candies (also Pidgeotto evolve at 50, which you'll probably have)
Evolving Rattata > Raticate and Pidgey > Pidgeotto give 500 exp, and (I think) Pidgeotto > Pidgeot giv 1000, but I'm probably wrong.
Don't train them. These are garbage mons, just catch them, evolve what you can, and trade the rest (both evolved and unevolved) to help the next cycle.
TLDR:
Evolve your Trash 'Mons for Exp, which helps you level, which helps you get better 'Mons and Items
