Aura of Silence taxes their Standstill suite while giving you a way to destroy problem enchantments like Standstill itself, making it excellent proactive disruption against a control mirror. Phyrexian Arena provides card advantage to grind through their counterspell-heavy plan since neither deck closes games quickly. Gerrard's Verdict loses value since this opponent doesn't rely on a fragile hand of key cards the way aggressive decks do, and discarding into a control deck with card draw is low-impact. Prioritize Duress to strip their Wrath of God or Standstill before committing threats, and be mindful of triggering their Standstill accidentally.
