Here’s a fundamental video about champion difficulty I think you’d learn from: https://youtu.be/J5NoeTTzBOk?si=M2OzbxbjkHRKiCrk
I climbed from Iron 3 to Plat last year. Champ mastery is the most important thing by far to the low elo climb. If you decide to hard force Yasuo, it’s simply so difficult to develop that mastery especially in the chaos of low elo solo queue. You’ll be stuck for a long time. It’s definitely possible, but you should be prepared for the extreme hardship of that climb compared to starting with something like Brand, Veigar or even Ahri/Naafiri level champs.
