How do you deal with salt?

Tonight a discard player spammed the sleepy emote in a Bo1 where I was able to dodge a counter and set up an urabrask forge. Obviously muting is the answer, but it made me think about how I keep my sodium levels low. I mean, I know I’ve certainly rolled my eyes at the third go for the throat even after slinging two or three equivalent cards their way.

So! Two questions:

How do you handle bad match-ups?

In particular, how do you deal with grindy matchups not going your way?
