Question for experienced players
How do you reach champion tier? I started playing competitive VGC when champions released for mobile, I was playing smogon for many years so I'm familiar with the basics but had never tried doubles. I'm really loving the experience so far.
Here's where I am stuck, I have 2-3 good teams, a few our cool, one is "meta" (rain) and one is anti-meta (mega staraptor+sand). I am able to reach the master ball tier with almost everything, however, in master ball tier I lose A LOT, I don't think it's a particular team's fault because with any team my win rate is around (30-40%), best I've reached is master ball 3. How do you get to the champions tier?
I tried teams from popular streamers or winner of other tours, but I feel having a team that won vs actually being able to use it are 2 separate things.
What would you guys recommend about reaching champions tier?
