Mono-Green Landfall goes wide with small landfall triggers and ramps into bigger threats, so Elegy Acolyte's 4/4 lifelink body stabilizes the race and turns on card draw once we start connecting. Ghost Vacuum can exile their Escape Tunnel or Fabled Passage from the graveyard once sacrificed, though its main value here is flexible graveyard hate against Icetill Explorer's replay plan. Dissection Practice's marginal pump/shrink is too small against their wide board, and Dark Knight's Greatsword is a slow investment in a matchup we want to win on pure card quality and life totals.
