Brotherhood's End sweeps their wide, cheap creature board (Stoneforge Mystic, Phelia tokens area, Thalia, Recruiter of the Guard) all with 3 toughness or less, dealing with their go-wide plan in one card. Grafdigger's Cage shuts off Recruiter of the Guard's tutor-to-hand is unaffected since it's library search to hand, not battlefield, but it does stop any reanimation or flashback-style recursion they might sideboard in, and is a cheap, low-opportunity-cost artifact. We cut Flusterstorm since they have no storm plan and Simian Spirit Guide since we want the full curve of answers more than a minor speed boost. Their Wasteland and Karakas disruption make resolving Atraxa quickly still our best path to victory.
