WU leans heavily on free/cheap countermagic (Force of Will, Daze, Consign to Memory) plus Stifle and colorless Clue tokens from Tamiyo, so Consign to Memory is premium here, stopping their colorless spells and triggered abilities (like Tamiyo's investigate or Phelia's exile trigger) for just U. Force of Negation and Mindbreak Trap are extra free counters to protect your threats from their own Force of Will or Teferi, Time Raveler shenanigans. Teferi, Time Raveler is a real problem since it stops your Force of Will from being cast at instant speed, so prioritize resolving your threats before they land it. Trim the narrow one-ofs that don't interact with their plan, keeping the core artifact engine untouched.
