Claim the Firstborn is poor here since their creatures are cheap one-for-one prowess threats not worth stealing, and Bloodtithe Harvester's -X/-X mode is often too slow against their burn-based removal race. Ghost Vacuum helps stem Arclight Phoenix-adjacent recursion and generic graveyard value while giving late-game flying blockers. The Legend of Roku's early exile-and-play mode helps rebuild after their burn spells clear our board, and it eventually becomes a resilient threat their burn can't easily remove. Prioritize Fatal Push and Witch's Oven/Cauldron Familiar to stabilize against their aggressive creature curve.
