Future Sight uncommon. Noncreatures with the morph ability create some interesting rules corner-cases. You can end up with a suspended land, for instance, if a morphed Cavern is hit with Delay while on the stack. What about Crucible of Worlds? Crucible of Worlds lets you play a land from your graveyard. So, you can play a Zoetic Cavern from your graveyard as a land. But it doesn???t let you play a creature from your graveyard, so you can???t play Zoetic Cavern as a creature.(Similarly, if you have Teferi in play and Zoetic Cavern in your hand, you can play Zoetic Cavern as a creature any time you could play an instant. But you can???t play Zoetic Cavern as a land any time you could play an instant.)
