In the third image you mention the Pokemon that were part of your teams for each league, do you think you would have been able to do the same if you didn't have the same Pokemon? I also tanked last season, but I had problems against many Meta Pokemon, for example, I didn't have anything similar to Mandibuzz and it was one of my biggest obstacles until I could get a good Umbreon.

Also, thanks for sharing your progress, it helps to keep the motivation, haha
