Izzet Leyline Aggro is a fast prowess-style deck that wants to go under you, so you need efficient blockers and resilient threats rather than a slow grindy plan. Surrak, Elusive Hunter is a strong 4/3 body for the cost that trades well in combat and draws cards whenever your creatures are targeted. Soul-Guide Lantern exiles a card from their graveyard, which can strip back Wild Ride's harmonize or graveyard recursion, while also cantripping later to smooth draws. Meltstrider's Resolve is risky since their creatures like Slickshot Show-Off and Elusive Otter can pump themselves mid-combat with noncreature spells, so it comes out along with the low-impact token generator Mole Man.
