Crumble to Dust

In Commander, Crumble to Dust earns a slot specifically when your meta is full of high-value utility lands — hitting Cabal Coffers, Nykthos, Shrine to Nyx, or Cavern of Souls and erasing every copy from the game is a level of thoroughness no other land removal achieves. Competitive Commander tends to pass on it because four mana at sorcery speed is too slow when games end on turn 3 or 4, but at a casual-to-focused table it's a genuine answer rather than a temporary setback. In Modern and Legacy it's a fringe sideboard option against land-based combo decks, though both formats move fast enough that the sorcery speed and four-mana cost make it hard to justify over cheaper alternatives. Pioneer offers similar logic — theoretical fits but rarely sees play. Crumble to Dust is at its best in the one format where games go long enough for a four-mana sorcery to matter and where a single land can take over the game.
