If my opponent has Ground Seal in play and I have a Crucible of Worlds, can I still play lands from my graveyard? I know Crucible of Worlds says nothing about targeting, so I assume it would not stop me from playing lands from my graveyard.
Some other cards that I assume would fall under the same roof as Crucible of Worlds are Karador, Ghost Chieftain and Gisa and Geralf.
