Tormod's Crypt denies them any graveyard value and is simply a stronger 0-cost artifact than Urza's Bauble when card quality matters less than tempo in a race. Your removal suite (Lightning Bolt, Incinerate, Shock) already answers their key threats like Hypnotic Specter and Nantuko Shade efficiently before they scale out of burn range. This is a race where your aggressive curve should outpace their disruptive, grindier plan, so the rest of the mainboard stays intact. Keep applying pressure early since Duress and Cabal Therapy can strip your hand if you give them time.
