Izzet Leyline Aggro leans on cheap spells and pump effects like Ancestral Anger and Wild Ride to push through damage quickly, so proactive disruption is valuable. Duress strips key combat tricks or Leyline of Resonance before they can use them to blow us out in combat. Ghost Vacuum exiles cards from their graveyard, denying recursion plays like Wild Ride's harmonize cost. We cut Dissection Practice's marginal effects and Dark Knight's Greatsword's slow equipment plan since we need to disrupt their proactive game plan rather than grind slowly.
