Mono-White Initiative is a hatebears deck full of taxing effects like Thalia, Guardian of Thraben and Archon of Emeria plus Chalice of the Void, so free spells like Daze become unreliable once Chalice locks out our cheap interaction. Prismatic Ending answers their threats with mana value 2 or less such as Thalia, Guardian of Thraben or Chalice of the Void itself, while Triumph of Saint Katherine is a large lifelink body that stabilizes against their aggressive initiative clock and can Miracle in cheaply. While Consign to Memory can counter Chalice of the Void or initiative triggers, Daze is unreliable under Thalia's tax and their fast mana, so Daze and a copy of Consign to Memory are trimmed.
