Mono Green Landfall ramps into large threats like Mossborn Hydra and Mightform Harmonizer, so Maelstrom Pulse is excellent unconditional removal for any problematic nonland permanent regardless of size. Glorious Decay's best mode here is exiling Esper Origins from their graveyard, which shuts off its flashback and replaces itself with a card. Witherbloom Charm's sacrifice-to-draw mode helps dig while its 5-life mode stabilizes against their aggressive landfall starts. Stir Up Trouble's extra cost is a liability early against their fast curve, and Obsessive Pursuit costs us life each upkeep while doing little to slow their landfall ramp. Keep the core removal suite since they have few ways to interact with our threats.
