GANJ4LF!!!! You are too fast xD Find some time to ladder, since you'll easily get into Silver Class at this rate.
Btw, the ladder points is referring to Glicko2 rating, so you actually have 1977, NOT 1865!
I'm glad that Mew set worked for you, although your Memento set was also awesome in giving your Sweepers the set-up opportunities they need. Which Pokemon worked better for you?
PS: ginganinja u nub, you need to reach top 100
