Azorius Standstill is a control deck that wants to Wrath of God our board after playing Standstill to force us to hold back. Although Prismatic Strands does not stop Wrath of God or exile removal since it only prevents damage, it can blank a key attacker if they bring in Exalted Angel from the sideboard. Patrol Hound trades down against their removal-heavy plan and doesn't pressure them enough before Wrath of God resets the board, so we make a small swap favoring resilience. Keep pressuring quickly; since Standstill punishes you for casting spells by letting your opponent draw three cards, don't trigger it with a cheap threat before overcommitting.
