Give me a commander/archetype/gimmick that I can play to get "good".
I constantly fuck up my sequencing and threat assessment, and stress out when it gets to my turn because I've spent the cycle thinking about everyone else's boards instead and then fuck up under the pressure to not sit around going "hmmmmm" for five minutes. All my decks feel slow but not grindy so they fold under pressure really quickly.

Anything that gets me thinking about nuance or paying better attention to the interactions of my own cards with each other
