Izzet Leyline Aggro is a fast, spell-heavy tempo deck that leans on Leyline of Resonance to double up targeted pump spells and Elusive Otter/Slickshot Show-Off with prowess-style triggers; Rest in Peace disrupts their graveyard recursion (like Wild Ride's harmonize cost) and denies incremental value, while Sheltered by Ghosts provides clean removal for key threats or Leyline of Resonance while granting lifelink and ward to stabilize our life total. Trim the slow, non-impactful Shared Roots and Dyadrine, since against a fast aggressive deck we need to prioritize resilient blockers and disruption over grindy mana sinks.
