Urza's SagaHow it works & interactions with other cards

A Land with a Timeline

Urza's Saga enters the battlefield with one lore counter, immediately triggering its first ability. As a land, you play it during your main phase when you have a land drop available; you do not cast it. It gains abilities cumulatively: at chapter I, it taps for colorless mana; at chapter II, it gains the ability to create Construct tokens. It retains these abilities as long as it remains on the battlefield, even after the subsequent chapters trigger.

Resolving the Final Chapter

When the third lore counter is added (usually after your draw step), the chapter III ability is put onto the stack. This ability allows you to search your library for an artifact card with a mana cost of exactly {0} or {1}. Importantly, this refers to the printed mana cost symbols, not just the mana value. Once this ability resolves and you put the artifact onto the battlefield, you must sacrifice Urza's Saga because its number of lore counters is equal to or greater than its final chapter number.

Common Pitfalls to Avoid

A common mistake involves the mana cost restriction in chapter III. You cannot search for cards with a mana cost of {X} or {U}, even if their mana value is 0 or 1, because those symbols do not match {0} or {1}. Additionally, while Urza's Saga has the 'Urza's' land type, it does not count as one of the three pieces required to power up Urza's Tower, Urza's Mine, or Urza's Power Plant.

When to Play Urza's Saga

Timing is crucial since the card is sacrificed after three turns. If you need to maximize your Construct production, ensure you have two mana available to activate the chapter II ability before the third lore counter is added. You can even activate the ability in response to the chapter III trigger being put onto the stack to get one last token before the Saga is sacrificed.

Interaction examples

Maximizing Construct Production

Urza's SagaConstruct

With two lore counters on Urza's Saga, you go to your next turn. After your draw step, a third lore counter is added, and the chapter III ability triggers. Before that ability resolves, you can tap Urza's Saga and pay two mana to create a Construct token. After the token is created, the search ability resolves, you find an artifact, and then you sacrifice Urza's Saga.

Understanding Mana Cost Requirements

Urza's Saga

When the chapter III ability of Urza's Saga resolves, you look through your library. You can pick a card like Mana Crypt (cost {0}) or Sol Ring (cost {1}). You cannot pick Hangarback Walker (cost {X}{X}) or Portable Hole (cost {W}), because their mana costs are not specifically {0} or {1}, even though their total mana values are low.
