This list went a perfect 6-0 in Swiss. The build is highly streamlined, running a lean mana package (Llanowar Elves, Icetill Explorer, Fabled Passage, Escape Tunnel) to rapidly develop the board and trigger Earthbender Ascension and Mightform Harmonizer. Ba Sing Se and Esper Origins provide late-game reach. Notably, flex slots like Shared Roots, Sapling Nursery, and the one-ofs give this list some resilience while the sideboard leans heavily on Mossborn Hydra for big-threat matchups and Torpor Orb for creature-ETB-heavy strategies.
For context, Mono Green Landfall posted a 55.8% non-mirror winrate over the past 60 days across 935 matches and 36 tournaments, making it a well-established tier presence in Standard right now.
