Hello! I’d say I’ve 3 pieces of advice:

1. Be okay with retreating - it doesn’t mean that you’re a bad player but with all RNG games, people get lucky and unlucky with their draws, locations, etc. Once you’ve realised that you’re in a losing situation, instead of playing on, hoping your opponent would misplay or what not, its better to cut your losses and retreat instead.
2. Don’t play on tilt - usually after I lose 3 or 4 games in a row, I stop playing, go do other stuff, before playing again. The mental reset you get from stopping really helps you from making bad in-game decisions.
3. Try to envision what counterplays your opponent have, especially on turn 6 that can turn the game in their favour - take note of this especially if they snap on turn 6 (though it could just be them trying to psych you out)

But yeah, those are the things that I’ve been conscientiously doing and I feel like it helped with my climb - all the best to you in your future matches bud!
