Rakdos Delirium relies on cheap graveyard-fueled threats like Nethergoyf, which grows with the card types in their graveyard, and Moonshadow, which enters as a 7/7 with six -1/-1 counters and loses one each time permanent cards hit their graveyard, so it gets bigger as the game goes on. Detective's Phoenix can also be recast from the graveyard. Obsidian Charmaw is a resilient flying clock that survives Lightning Bolt and punishes their nonbasic lands, since its enter trigger destroys a fetch or Blood Crypt. Stubborn Denial is cut because it can only counter noncreature spells, and most of their threats are creatures. We lean on direct pressure and removal from our own Lightning Bolt and Leyline Binding instead.
