Enchantment, 2BBB (5) Players can't play lands. If a land would come into play, instead it doesn't. At the beginning of each upkeep, any player may sacrifice two lands or pay 5 life. If a player does either, sacrifice Worms of the Earth.1 The ground collapsed, leaving nothing but the great Worms' mucous residues.

A land which somehow phases out will remain phased out since it cannot return to play. It will try again during the next turn. [D'Angelo 2002/01/11]
A land which is somehow put into a Safe Haven will leave the game forever if it tries to return while Worms of the Earth is in play. [Duelist Magazine #6, Page 132]
The ability triggers during each player's upkeep, not just your own. [D'Angelo 2006/05/13]
If you play a spell/ability like Untamed Wilds which lets you put a land into play, the effect fails. With Untamed Wilds you still shuffle the library. [Duelist Magazine #6, Page 132]
Eureka will not allow a land to enter play. [WotC Rules Team 1995/06/15]
