Naya Initiative floods the board fast with creatures like Caves of Chaos Adventurer and Undermountain Adventurer, so Engineered Explosives set for three or four mana is a clean sweeper against their threats and Trinisphere. Pithing Needle should name their Karn, the Great Creator to deny them a second copy of Trinisphere or another artifact from outside the game. Consign to Memory answers the wave of enter-the-battlefield triggers this deck relies on, including Caves of Chaos Adventurer and Undermountain Adventurer's initiative triggers. Ugin is too slow to matter against a deck that can curve out and attack before turn four, so it comes out alongside other reactive, high-cost cards.
