Mono Green Landfall wants to go bigger and ramp into Mossborn Hydra and Mightform Harmonizer; Erode is clean, efficient removal that kills their key threats while leaving Amalia's lifegain engine untouched. Cathar Commando answers Earthbender Ascension and Sapling Nursery before they snowball, and Ghost Vacuum both blunts Keen-Eyed Curator's growth and gives you a cheap way to interact. Goldmeadow Nomad, Aunt May, and Starscape Cleric are the weakest bodies against a deck racing to bigger creatures rather than playing a grindy lifegain mirror. Keep the core engine (Amalia, Case of the Uneaten Feast, Lunar Convocation, Haliya) fully intact since this matchup is still about resolving your value pieces faster than they ramp.
