Eldrazi leans heavily on Chalice of the Void to shut off our cascade plan, so Ingot Chewer's ETB destroying target artifact is a clean, efficient answer that can even be evoked for {R} if we need to save mana. We trim two copies of Trumpeting Carnosaur since its double-red cost is awkward, and we already have plenty of other threats in the mainboard for card advantage. Watch for Chalice of the Void set to 3 shutting off Violent Outburst, so sequence cascade spells before they can land that Chalice count. Our own cascade chains can find answers to Kozilek's Command indirectly, but the real plan is racing before Chalice locks us out.
