The most obvious switch is Thormund in for Winston. Thormund is practically a must in mono-La Junta, and winning the round will block a lot more than 3 damage min 3. Also, Winston's 6 power without manipulation is just too low to scare anyone.
Other than that, your deck looks pretty solid. Pay attention to the decks you're facing. Heavy damage decks suggest the introduction of Jane Ramba for a bit of DR (probably for Bruce, who's basically just a Wardog plus one damage after all). If you're meeting a lot of SOA, consider replacing Trish with Nahomi. Or you might want to mix it up with Archibald if pillz manipulation is your style.
