Lands is a pure land-based combo/control deck with almost no spells to counter, relying on Dark Depths plus Thespian's Stage to make a 20/20 Marit Lage token and Urza's Saga to fetch artifacts, so Meltdown at X=0 or X=1 is strong against their Mox Diamond and any small artifacts fetched by Urza's Saga. Ratchet Bomb can be used at the right counter count to sweep Construct tokens and small artifacts, but it cannot answer Marit Lage, which is indestructible. Force of Negation can stop a crucial Crop Rotation or other key noncreature spell on their turn. Into the Flood Maw and Spell Pierce are nearly dead since they have very few relevant permanents to bounce and no spells worth taxing, and your Wasteland is already strong disruption against their nonbasic-heavy manabase, so this plan stays small and conservative.
