Are the lands like shambling vents and stirring wildwood good in edh, are they worth it?
On their own? Not really. Mutavault is probably the best manland for obvious reasons. None of the others are really impressive unless you have a particularly good reason for playing them.
Creeping Tar Pit, Dryad Arbor, Mishra's Factory and Inkmoth Nexus are top five with Mutavault in my opinion. The rest can be good depending on the deck and the meta. If multiple people are playing wraths everygame or if someone is playing wrath.deck then they are invaluable likewise to indestructible effects. And they are good against aggro decks if you are playing wraths. Also good if people play lots of planeswalkers as the sorcery speed effect makes it unanswerable by said planeswalkers. Obviously they're good if you're playing lands.deck. That said, most come into play tapped and you risk your land to more types of removal when you activate it, so these factors should be considered as well. For instance they aren't as good if the meta is heavy in spot removal and/or fast combo decks.
