Mono Red Madness wins by chaining cheap spells into Guttersnipe and Kessig Flamebreather for direct damage, so Relic of Progenitus is useful graveyard hate: exiling all graveyards stops Sneaky Snacker from returning when they draw their third card in a turn, and it shuts off the flashback on Faithless Looting and Lava Dart. It also draws us a card when we use it, which makes it fine late-game filler. Call Damage Control lets us rebuy key permanents like Giant's Boulder or Expedition Map that get raced away, smoothing out the grind. Crop Rotation is too slow against a deck trying to kill us quickly, and Barrels of Blasting Jelly's 5-mana activation is far too clunky to matter before we're dead. Prioritize Tron assembly and life gain from Bramble Wurm and Boulderbranch Golem to outlast their burn.
