Rakdos Delirium relies heavily on graveyard synergies like Nethergoyf, Moonshadow, and Detective's Phoenix's bestow-from-graveyard ability, so Keen-Eyed Curator can exile their graveyard cards one at a time to slow delirium and shrink Nethergoyf and Moonshadow's counter-removal triggers. Kraul Harpooner is a solid 3/2 reach blocker against their aggressive curve and grows if our own graveyard fills up, giving us a way to stabilize the board. Their deck is full of efficient removal (Lightning Bolt, Flare of Malice) and discard (Thoughtseize), so don't overextend into Flare of Malice, which forces a sacrifice of our biggest creature or planeswalker. Keep the core combo plan intact since this matchup is primarily a damage race decided by who can protect their board state longer.
