An above 50% winrate will get you out of bronze if you win enough games. If you’re in the depths of bronze 5 it will take many hundreds of games. Btw this is assuming you never dodge drafts or DC in game (that’s 500 points each, although in the long run you do get those back over time).
Run it down azmo is unbeatable by bronze players. If they knew how to counter it, they wouldn’t be bronze.
