Although Urza's Saga has the Urza's land type, it doesn't interact with Urza's Tower, Urza's Mine, or Urza's Power Plant.
If Urza's Saga loses all of its chapter abilities but is still a Saga, perhaps due to a card like Blood Moon, it will immediately be sacrificed.
Urza's Saga is a land, so it can only be played as a land. It cannot be cast as a spell.
Even though Urza's Saga is a land, it is also still a Saga, and it will be sacrificed after its last chapter ability resolves.
Urza's Saga gains an ability from its first and second chapters. It keeps those abilities for as long as it's on the battlefield.
