Maverick disrupts early with 4 copies of Thoughtseize and uses Wasteland to deny your mana, so Veil of Summer protects your hand from their discard spells while dodging any incidental black removal like Fatal Push or Snuff Out. Faerie Macabre's discard-to-exile ability interacts with their Stitcher's Supplier-fueled graveyard plan feeding Hogaak, Arisen Necropolis, letting you strip a key piece before they cheat in an 8/8 trampler. Cutting the redundant Omniscience and Acererak copies keeps your deck focused on resolving the primary combo quickly, since Maverick's disruptive hand attacks and Wasteland mana denial punish a slow, grindy approach more than a proactive one.
