Maverick grinds with efficient creatures like Orcish Bowmasters, Wight of the Reliquary, and Hogaak, Arisen Necropolis (cast from the graveyard with convoke and delve), plus disruption from Thoughtseize and Wasteland, so we want more proactive answers and less tempo-based countermagic. Triumph of Saint Katherine is a lifelink 5/5 that stabilizes against their creature pressure and can come down early off Miracle for a two-mana blowout. Prismatic Ending answers problematic permanents like Sylvan Safekeeper or Elvish Reclaimer by exiling based on mana value and colors spent. Daze loses value since Maverick is not relying on fast free spells to race us, and Stifle has few profitable targets against their creature-based grind, so both are trimmed for proactive answers.
