Selesnya Landfall's whole plan revolves around resolving and protecting Earthbender Ascension and Mightform Harmonizer to pump an ever-growing board; Get Lost is unconditional removal that answers either at instant speed, and the two Map tokens it gives up are meaningless against our proactive gameplan. Leatherhead, Swamp Stalker's hexproof counter dodges their removal (Erode) and its trigger can strip an Earthbender Ascension engine piece once it connects, while its 5/4 trample body races their go-wide creatures. We shave slower, clunkier cards (Aang, at the Crossroads, Formidable Speaker, Imodane's Recruiter) that don't interact with their key enchantments, keeping our airbending suite intact to tempo out their threats.
