UR Aggro wants to race with cheap spells and grow Slickshot Show-Off / Stormchaser's Talent-adjacent threats, but Stormchaser's Talent itself is banned so their curve leans on Temur Battlecrier and Spider Manifestation for the aggressive plan; Defend the Rider's hexproof/indestructible mode protects our key blockers and attackers from their removal (Burst Lightning, Hex Magic-fueled burn). Doubling Spell Pierce punishes their low curve early when they're tapped out for a two-drop. Lumbering Worldwagon is too slow against a tempo deck that wants to close fast, and Rogue's Passage doesn't matter when we're racing rather than being stonewalled. Keep the core engine intact since Garruk's Uprising and Frenzied Baloth are exactly the resilient, hasty threats that punish their lack of sweepers.
