Mono-Green Landfall runs many nonbasic lands (Ba Sing Se, Escape Tunnel, Fabled Passage) that trigger Sunspine Lynx's ETB damage, and its lifegain-prevention clause blanks any lifegain shenanigans from Rapid Rescue. Hexing Squelcher's Ward makes our threats stickier against their removal-light, creature-heavy plan and helps close a straightforward race. We trim our smallest burn spells since their creatures (Mightform Harmonizer, Icetill Explorer) are often too big to profitably 2-for-1 with Shock or Lightning Strike, favoring bigger threats and removal we keep.
