Gruul Delirium is a creature-heavy midrange aggro deck that doesn't lean on key noncreature spells early, so Duress is largely a blank and comes out along with a slow Winternight Stories. Qarsi Revenant stabilizes against their aggressive curve of Patchwork Beastie and Wildfire Wickerfolk while gaining life to offset their reach from Channeled Dragonfire and Burst Lightning. Shoot the Sheriff cleanly answers their small, pump-protected creatures at instant speed before Blossoming Defense can save them. Keep Bitter Triumph and Requiting Hex in as your main removal against bigger threats like Summon: Brynhildr.
