Lands relies on Wasteland/Ghost Quarter-style land denial and grinding engines like Life from the Loam and Urza's Saga rather than creatures, making most of our removal and graveyard hate largely irrelevant since they have very few creature or graveyard targets. The extra Fatal Push copies are for the few creatures they do present: the Construct tokens from Urza's Saga (mana value 0, so Push kills them even without revolt) and Icetill Explorer (mana value 4, so it needs revolt). Fatal Push cannot deal with Marit Lage from Dark Depths, since the token is indestructible and Push only destroys. We have to stop Dark Depths some other way, such as Wasteland on the land itself or racing. Wasteland is still crucial on our side to fight their manabase, so we keep our full land count intact. This is largely a race where our own threats (Hogaak, Moonshadow) need to come down and attack before their engine assembles Thespian's Stage/Dark Depths or a Tabernacle lock, so we keep the core gameplan mostly unchanged.
