Selesnya Landfall scales up creatures like Mightform Harmonizer and Mossborn Hydra through repeated land drops, so Voice of Victory's static ability shuts off their Erode and other instant-speed tricks during our attacks while adding pressure. Erode gives us clean removal for their biggest threat before Earthbender Ascension triggers snowball out of control. Doc Ock's Tentacles doesn't fit our low curve, and Basilisk Collar's lifelink is less impactful against a go-wide landfall deck that can out-block us with bigger bodies. Race aggressively and use removal to stay ahead of their land-fueled scaling.
