Just came back after a long hiatus, used to be gold. Playing with Bronze people is awful, been maining Brand mid (my favorite champ) but he gets banned a lot at this elo.

Any ez mode builds for jungle and other cheek clapper mids I should look into? Looking for super cheese builds to get out of Bronze asap (champs that aren't heavily banned at this elo)

viego and sylas
give it 100 games and you should be around plat elo by then.
if you manage to get under 60% winrate on those champs, especially viego, just give up climbing and playing in general.

since viego's release, there's ppl that were silver-gold for 6 years suddenly playing in d4.

here is some real advice to climb:
Don't look for cheese builds or OP champs. While you may climb a couple divisions, the gains are temporary.
Learn the fundamentals of the game and you will improve drastically faster than abusing OP shit. Watch some skill capped, pro/high elo streamers, and watch your own VODs to analyze your mistakes.
