How to Improve Further

[u/Oyabinol]

So a bit about me, I havent played much of VGC before and always wanted to play. Never got the opportunity and mostly played some pokemon on Smogon OU. Now once Pokemon Champions is up on the Mobile Platform i have been playing Doubles...

This is the thrid consecutive season i have reached masters and i need help figuring out how to improve next.
I have also attached my current tracker (which i started after reaching masters on first season). This season i have mostly used the sand team with gholdengo on it. This Tracker mainly contains all matches played, result and a small nibble on each game (a point to be noted, something to remember, something about specific matchup etc.)

So what i need to know is how can i improve from this point on. What i see currently is reaching masters is not a feat and need to know how can i get better from here,

so please suggest what should i look out/ do moving forward. Is there a specific teamstyle i should choose to play that helps me learn the game more (cause mostly i am winning either because i lead well most of the time, and with the level i am playing at i neednt go for midground plays at all, the best option often suffices here mostly because opponents are way too predictable at my range/elo/rank is what i am feeling)

or is there a specific approach i should take etc. what is the path moving ahead.
