Saga di Urza

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.

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.

Urza's Saga is a land, so it can only be played as a land. It cannot be cast as a spell.

While resolving the chapter III ability, you can find only a card with actual mana cost {0} or {1}, not mana value 0 or 1. For example, you couldn't find a card with mana cost {U} or one with mana cost {X}.
