Similar to the Rakdos Delirium matchup, BR is a graveyard-aggro deck with Thoughtseize and efficient removal, so we lean into our storm plan with Grapeshot and Empty the Warrens to finish quickly before Dark Matter Manipulator and Nethergoyf scale up. We trim a Twinned Vision and Valakut Awakening since they're slower pieces that don't close the game fast enough. Their sideboard has Obsidian Charmaw, a creature that destroys one of our nonbasic lands when it enters, and Unholy Heat, which can only target creatures or planeswalkers, so it mostly misses our spell-based gameplan apart from Ral. Keep pressure high and race their graveyard value engine.
