Eldrazi's Chalice of the Void set at two, three, or four can blank a big portion of our deck, including Tibalt's Trickery (which costs 2) and our cheaper cascade spells like Violent Outburst and Throes of Chaos, so we want to trim down on narrow cards and bring in answers to their artifacts. Ingot Chewer's evoke mode destroys Chalice of the Void for just {R}, which is crucial against their mana-denial plan. Fury's ETB damage can clean up their small Eldrazi Spawn tokens or Glaring Fleshraker, and double strike lets it trade up in combat against their bigger threats. Maelstrom Wanderer is an eight-mana double-cascade spell that's just too slow against Ancient Tomb-fueled Reality Smasher starts, so we cut it alongside Tibalt's Trickery.
