Selesnya Landfall is a fast aggressive deck that floods the board early with Llanowar Elves and Sazh's Chocobo while growing threats through Earthbender Ascension and Mightform Harmonizer off repeated landfall triggers. Fire Magic comes in as instant-speed sweeper removal to pick off their mana dorks and early creatures before they can snowball, buying the time needed to assemble Omniscience. Spider-Sense provides additional flash-speed interaction to protect our creature combo pieces from removal spells like Erode and to answer instant or sorcery spells and triggered abilities during their turn. Prismari Charm and Winternight Stories are too unfocused and slow for this matchup, as we need every card to either accelerate our combo or stall their board. Post-board they add Sheltered by Ghosts as removal that grants ward {2} and Dawn's Truce to protect key creatures, so prioritize removing threats before they can suit up — once Omniscience resolves, free spells will overwhelm anything they have left.
