Selesnya Landfall ramps into large, resilient threats via Mightform Harmonizer and Mossborn Hydra plus the Ba Sing Se/Earthbender Ascension engine, so Sear and Broadside Barrage give us clean, instant-speed answers to bigger bodies that Burst Lightning alone can't finish off. We make a light swap, trading one Multiversal Passage for speed since this matchup is a race against their landfall snowball, and Secret Identity is a lower-priority trick compared to hard removal against their growing creatures. Keep the full core engine intact since applying early pressure before their lands and Earthbender Ascension triggers accumulate is our best path to victory.
