Eldrazi is a mana-ramp creature deck that leans on Chalice of the Void and Ancient Tomb rather than free spells, making Daze largely dead since they can simply pay the extra mana or just leave it open. Prismatic Ending can exile Chalice of the Void (mana value 0 on the battlefield) with a single color, and by spending both white and blue it can also exile two-drops like Wastescape Battlemage or It That Heralds the End. This is crucial since Chalice can lock out our cantrips. It cannot reach Thought-Knot Seer, which has mana value 4. Triumph of Saint Katherine is a lifelink 5/5 body that stabilizes against Reality Smasher and Eldrazi Linebreaker beatdown and can be cast off its Miracle cost for value. Consign to Memory does hit their colorless Eldrazi spells like Reality Smasher and Thought-Knot Seer, but we are prioritizing proactive removal and life gain over tempo counters against their bigger bodies, so we trim it alongside Daze.
