Rakdos Delirium leans on graveyard value engines and cheap removal (Lightning Bolt, Flare of Malice). Nethergoyf scales with the card types in their graveyard and can escape from it, while Moonshadow grows back toward 7/7 whenever permanent cards hit their graveyard, so we are not building the plan around graveyard hate and Soul-Guide Lantern-style answers aren't included here. Pithing Needle is a small but real tool to shut off a problematic activated ability, such as Mishra's Bauble or Street Wraith's cycling; mostly it's a low-cost swap. We keep the plan minimal and lean on our proactive game plan, trimming only the weakest mainboard card, Paradise Mantle, to fit it in.
