UR Aggro is a cantrip-fueled tempo deck built around Slickshot Show-Off and cheap spells rather than artifacts/enchantments, so answers are limited; Cathar Commando still trades favorably in combat against their small creatures (Pompous Battlemage, Callous Sell-Sword, Elusive Otter) thanks to flash and 3 power. Ghost Vacuum provides cheap, repeatable graveyard exile to slow their Wild Ride harmonize recursion and gives late-game card filtering. Goldmeadow Nomad and Aunt May are too fragile to block their evasive or pump-fueled attackers profitably, so they're trimmed for more resilient bodies; the lifegain plan (Case of the Uneaten Feast, Lunar Convocation) is your main way to outlast their burn and tempo damage, so it stays untouched.
