Naya Delirium wants to fill its graveyard to turn on Fear of Missing Out and Wildfire Wickerfolk while pressuring you with a steady stream of creatures, so Clarion Conqueror is a great flying blocker that survives their sideboard Pyroclasm (2 damage) even though it will die to Splatter Technique-style bigger sweepers. Erode is unconditional removal for their best threat, and Spell Pierce catches a Break Out or Bushwhack while they're tight on mana. Requisition Raid can pick off Wildfire Wickerfolk, since it is an artifact creature. Cut Helping Hand, Practiced Offense, Winternight Stories, and Gran-Gran to lean into efficient removal and evasive blockers instead.
