Selesnya Landfall is a very similar landfall mirror, relying on Earthbender Ascension's enters trigger (earthbend 2 and a basic land) and Mightform Harmonizer's landfall doubling to outscale us. Torpor Orb only stops abilities triggered by creatures entering, so it does nothing against their enchantment-based engine and stays in the sideboard. Instead we bring in Origin of Metalbending, which can destroy Earthbender Ascension or Dyadrine, Synthesis Amalgam, and its other mode gives a creature indestructible to blank their Erode. Warg Tactics protects our key creatures the same way, since the hexproof mode makes Erode fizzle and the counter and trample add pressure. We cut Snakeskin Veil, which Origin of Metalbending and Warg Tactics replace with more flexible protection, and Elven Passage, since we don't need extra fixing in this grindy landfall race.
