Surprised you haven't made it yet, the amount of mana required to win a Diamond league is not that high. I guess the key is being risk-averse - you can't have a negative season or you'll get demoted, and no offense but you are not a particularly risk-averse user lol

But I think you are often directionally correct so if you set a clear goal you can probably do it

@SaviorofPlant I would have easily gotten there if leagues weren't rigged for like the first 1.5 years I was on this site
