  Official Ruling
  Crucible of Worlds doesn't allow you to activate abilities (such as cycling) of land cards in your graveyard.
• WWizards of the Coast2018-07-13
  Official Ruling
  Crucible of Worlds doesn't change the times when you can play those land cards. You can still play only one land per turn, and only during your main phase when you have priority and the stack is empty.
