"Level 20 player seeking for advice (pt.2)"

#PokemonGO: I did a thread when iI was level 16 some days ago, and someone told me to ask again once I achieved level 20, so here I am. The thread i've mentioned can be found here.So, i'm just searching for what to do about giving candies to my pokémon, gym strategies and just general advice. This is my pokémon roster.I'm also having trouble finding what should i spend pokécoins with (I have 180 now). I think that buying a space extension for my bag would be great because i run out of space easily, but i've read somewhere that it isn't worth it. I have two lucky eggs that I won't use anytime because i'm collecting a lot of pidgey candies, three lure modules and three incenses. What should I buy? Thanks in advance! via /r/TheSilphRoad http://ift.tt/2gDubwS
