Selesnya Landfall relies on cheap creatures like Llanowar Elves, Sazh's Chocobo, and Icetill Explorer to enable Earthbender Ascension and Mightform Harmonizer, so Day of Black Sun sweeps their early mana creatures and small bodies before they scale out of control. Preacher of the Schism's deathtouch is a great long-term blocker against their pumped attackers while generating card advantage. Winternight Stories and the single M.O.D.O.K. are too passive against a deck trying to go wide and tall quickly, and one Archenemy's Charm covers their rare bigger threat. Keep Bitter Triumph and Requiting Hex for efficient early removal.
