Azorius Control has very few creatures, so cheap creature removal like Fatal Push has few worthwhile targets and is the weakest part of your deck in this matchup. Keep Bitter Triumph, since it also destroys planeswalkers and answers The Wandering Emperor and Teferi, Hero of Dominaria. Unholy Annex/Ritual Chamber stays in too: Temporary Lockdown only exiles nonland permanents with mana value 2 or less, and Supreme Verdict only destroys creatures, so neither answers the Room cleanly. Duress is excellent proactive disruption. It can take their counterspells (No More Lies, Dovin's Veto), sweepers (Supreme Verdict) or planeswalkers before you commit threats. Keep Thoughtseize and your efficient threats like Kaito and Sheoldred, since resolving a hard-to-answer threat is the path to victory against control.
