A guide to Legacy’s extra-turns combo
Legacy’s extra-turns combo is a spell-heavy strategy built around taking additional turns, converting those turns into cards and mana, and eventually winning before the opponent can recover. It is less standardized than Delver, Reanimator, or Sneak and Show, so different pilots may use very different engines while pursuing the same goal.
The most recognizable versions combine a turn spell such as Final Fortune or Chance for Glory with Sundial of the Infinite. Other builds use Mystic Sanctuary to recycle Time Warp or Temporal Manipulation, usually alongside cantrips, fetchlands, and a mana engine. These approaches reward careful sequencing rather than automatic combo assembly.
The deck is a good fit for players who enjoy planning several turns ahead, protecting a fragile setup, and exploiting narrow timing windows. It can be tuned for local metagames, but it demands practice because a single missed land drop or poorly timed cantrip can end the game.
What the deck is trying to do
The central plan is to make an extra turn matter. A turn spell by itself is often expensive, and a card such as Final Fortune carries a game-losing drawback. The deck therefore needs a way to gain value immediately through attacks, planeswalkers, card selection, or a repeatable loop.
Sundial of the Infinite provides the cleanest interaction with Final Fortune and similar effects. After the “lose the game” trigger is placed on the stack during the end step, activating Sundial ends the turn. The trigger disappears with the rest of the stack, allowing the pilot to continue playing. This does not create unlimited turns by itself: the deck still needs another extra-turn spell, enough mana, and a way to win.
A second route uses Mystic Sanctuary. With three or more other Islands, the land enters untapped and can place an instant or sorcery from the graveyard on top of the library. Fetchlands, Brainstorm, Ponder, and other draw effects can then help recast a turn spell. This package is slower and more demanding, but it fits naturally into a control shell.
The core packages
A Sundial build usually starts with a small number of extra-turn cards, several copies of Sundial of the Infinite, and a high density of cheap interaction. Final Fortune costs only two mana, making it attractive when the deck can protect a quick setup. Chance for Glory costs more, but its indestructible clause can make a decisive attack safer.
The Mystic Sanctuary version wants fetchlands and a substantial blue mana base. Time Warp and Temporal Manipulation are expensive, so the deck often includes cards that produce extra mana or generate exceptional card selection. High Tide is a possible direction, although combining a turn loop with a traditional High Tide plan can make the deck vulnerable to graveyard hate and countermagic.
A hybrid list can use both packages, but every additional engine increases the number of cards that do little when drawn alone. The strongest lists establish a clear priority: either assemble Sundial and a risky turn spell quickly or play a control game until Sanctuary recursion becomes reliable.
The card’s place in Legacy history can also matter when choosing unusual inclusions. The Legacy card history surrounding format staples shows how formerly overlooked cards can gain relevance when new engines or metagames appear.
Comparing the main approaches
| Approach | Primary pieces | Strengths | Weaknesses |
|---|---|---|---|
| Sundial and Final Fortune | Sundial of the Infinite, Final Fortune, Chance for Glory | Low-cost setup and a clear timing interaction | Requires several independent pieces and leaves the pilot short on resources |
| Mystic Sanctuary recursion | Mystic Sanctuary, fetchlands, Time Warp or Temporal Manipulation | Fits a blue control shell and reuses powerful spells | Slow, mana-intensive, and vulnerable to land disruption |
| High Tide turns | High Tide, turn spells, cantrips, mana acceleration | Can generate explosive turns and large mana totals | More complex, exposed to graveyard hate and stack interaction |
| Planeswalker value | Extra-turn spells, Jace, the Mind Sculptor, Teferi, Temporal Pilgrim | Turns additional turns into cards and board control | May win slowly and can dilute the combo package |
Building the mana and card selection
The mana base needs to support both early interaction and expensive sorceries. Basic Islands help against Wasteland and Blood Moon, while fetchlands support Brainstorm and Mystic Sanctuary. A list that relies on Sanctuary should avoid filling its graveyard with too many cards that it cannot afford to lose to opposing Surgical Extraction.
Cantrips are the deck’s consistency engine. Brainstorm is strongest with fetchlands, while Ponder helps locate lands, protection, or the missing combo component. Preordain is less explosive but improves opening hands without requiring a shuffle effect. Consider carefully whether each cantrip is finding a specific card or merely hiding a weak hand.
Mana acceleration changes how the deck approaches the game. Lotus Petal can produce a fast Sundial or turn spell, but it is poor in a long game. High Tide, Sapphire Medallion, or artifacts may provide more sustained mana, though they require additional deck space. Avoid treating acceleration as free: the deck still needs enough blue sources to cast Force of Will and early setup spells.
The win condition can be modest. Once the opponent is locked out or the pilot has several extra turns, a planeswalker, creature, or repeated attack is usually sufficient. Some lists use Jace, the Mind Sculptor to control the board and end the game, while others rely on Murktide Regent or a small creature package that doubles as early defense.
Sequencing the combo
Before casting an extra-turn spell, identify the exact reason for doing so. If the turn is only being used to draw another card, the play may be weaker than holding up countermagic. If it enables an attack, a planeswalker activation, or a Sanctuary setup, the exchange becomes much more attractive.
With Sundial, let the end-step loss trigger appear before activating the artifact. Ending the turn too early can prevent useful end-step actions, while activating it at the wrong time may fail to remove the relevant trigger. The pilot should also account for Sundial’s tap requirement: if it is tapped by an opposing effect, the safety mechanism may not be available.
Mystic Sanctuary sequencing is more about land management. Fetchlands should often remain on the battlefield until the turn in which Sanctuary is needed. Playing Sanctuary too early can expose it to Wasteland, and fetching all basic Islands immediately may leave no way to trigger the land’s ability later. Brainstorm can draw the recycled spell after Sanctuary places it on top, but the pilot must have enough mana to cast both cards and maintain protection.
Playing through disruption
The deck is especially vulnerable while assembling its pieces. Force of Will, Force of Negation, Daze, Spell Pierce, and Flusterstorm can all stop a key turn spell. Thoughtseize and Duress attack the hand before the combo is ready, while Wasteland can break up a Sanctuary plan or cut the deck off a critical color.
Post-sideboard games require a shift in priorities. Veil of Summer helps against discard and blue interaction, Defense Grid can make a combo turn safer, and additional basic lands reduce the cost of opposing Wasteland. Graveyard hate is useful against Sanctuary recursion, but it does not necessarily answer a Sundial-based build.
Do not force the combo into open mana when a slower line is available. Extra-turn decks can win by resolving a planeswalker, trading resources with removal, and waiting until the opponent has fewer answers. A pilot who treats every game as a race will often lose to interaction that could have been played around.
Practical recommendations for testing
The strategy improves quickly when games are reviewed turn by turn. Track whether a loss came from missing a land, choosing the wrong tutor target, running out of protection, or misusing the extra turn. That information is more useful than simply adding another copy of the card that looked impressive.
- Start with one primary engine before adding a secondary combo package.
- Test opening hands against Wasteland, discard, and countermagic.
- Keep fetchlands available when Mystic Sanctuary is central to the plan.
- Practice resolving Sundial triggers without shortcuts or timing errors.
- Use sideboard slots for both stack protection and anti-graveyard tools.
Local events are the best place to learn which version fits the surrounding metagame. Tournament schedules, coverage, and event announcements can help place testing in a competitive setting rather than relying only on goldfishing.
Bring a carefully tuned list to the next Legacy event, record the hands and decisions that shaped each match, and refine the engine through real games. Extra turns reward preparation, and every round provides another chance to turn a narrow interaction into a winning sequence.
