Hi all,
Ty everyone for the replies, much appreciated and helpfull.
To answer the question, i got everything beat, no lvl cap, 5 comp mons ev trained of wich 1 is lvl 100 rest stil grinding and i am currently expanding that list also have a false swipe lvl 100 smeargle x3 catcher and a pickup meowth x5 almost lvl 100. my comps are x5.
So yes i've been doing stuff that is listed in this guide, even some gtl flipping.
I stil strugle with gym rematches but that should be over soon when my other comps are lvl 100, currently can beat a few of the gym rematches just with OHKOing with a heracross lvl 100, but i am obvisouly not fully ready yet to beat all gyms (i will soon tough).
But i feel like i made some inefficient farming choices in the past, the answers are defintly helpfull.
I'll use the tips listed thanks everyone for this update.
