Taigam, Ojutai Master — ruling 1

If Taigam leaves the battlefield after it attacks, its last ability won't trigger whenever you cast an instant or sorcery spell from your hand this turn. If it leaves the battlefield after the spell has gained rebound, that spell will still have rebound. Once the card is exiled, rebound's delayed triggered ability will trigger at the beginning of your next upkeep even if you no longer control Taigam.

Taigam, Ojutai Master — ruling 2

If Taigam is killed in response to you casting a spell, the ability will still trigger and your spell will gain rebound if Taigam attacked.

Taigam, Ojutai Master — ruling 3

Casting the card again due to rebound's delayed triggered ability is optional. If you choose not to cast the card, or if you can't (perhaps because there are no legal targets available), the card will stay exiled. You won't get another chance to cast it on a future turn.

Taigam, Ojutai Master — ruling 4

If a spell with rebound that you cast from your hand doesn't resolve for any reason (either because another spell or ability counters it or because all its targets are illegal as it tries to resolve), none of its effects will happen, including rebound. The spell will be put into its owner's graveyard and you won't get to cast it again on your next turn.

Taigam, Ojutai Master — ruling 5

If a replacement effect (such as the one created by Rest in Peace) would cause a spell with rebound that you cast from your hand to be put somewhere other than into your graveyard as it resolves, you can choose whether to apply the rebound effect or the other effect as the spell resolves.

Taigam, Ojutai Master — ruling 6

If a spell moves itself into another zone as part of its resolution (as Teferi's Protection, All Suns' Dawn, and Beacon of Unrest do), rebound won't get a chance to apply.

Taigam, Ojutai Master — ruling 7

At the beginning of your upkeep, all delayed triggered abilities created by rebound effects trigger. You may handle them in any order. A spell you cast this way resolves before you can cast the next one, so one rebounded spell can't target another. Timing permissions based on the card's type (if it's a sorcery) are ignored. Other restrictions, such as "Cast [this spell] only during combat," must be followed.

Taigam, Ojutai Master — ruling 8

If you cast a card from exile, it will go to its owner's graveyard when it resolves, fails to resolve, or is countered. It won't go back to exile.

Taigam, Ojutai Master : règles, fonctionnement et interactions (MTG)

Taigam, Ojutai Master is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

Official card text

Instant, sorcery, and Dragon spells you control can't be countered. Whenever you cast an instant or sorcery spell from your hand, if Taigam attacked this turn, that spell gains rebound. (Exile the spell as it resolves. At the beginning of your next upkeep, you may cast that card from exile without paying its mana cost.)

Complete guide

Taigam, Ojutai Master is a powerful legendary creature that ensures your most impactful spells resolve without interference. By leading the charge in combat, he grants your magic the longevity of the Ojutai through the Rebound mechanic.

Uncounterable Spells

Taigam provides a static protection effect for your Instants, Sorceries, and Dragon spells. While Taigam is on the battlefield, these spells cannot be countered by spells or abilities, such as a Counterspell. Note that this only applies while the spell is on the stack; it does not protect the spells from being exiled or having their targets removed.

The Rhythm of Rebound

Taigam's second ability triggers whenever you cast an instant or sorcery spell from your hand, provided Taigam attacked earlier in the same turn. When the spell resolves, Rebound exiles it instead of putting it into your graveyard. At the start of your next upkeep, a delayed trigger allows you to cast that card again for free. If you cast a spell this way from exile, it goes to the graveyard upon its second resolution.

Common Pitfalls

A spell only rebounds if it successfully resolves. If a spell's targets become illegal before it resolves, it is put into the graveyard and Rebound never triggers. Additionally, Taigam must be on the battlefield at the moment you cast the spell from your hand to grant it Rebound. If he leaves the battlefield after attacking but before you cast your spell, the spell will not gain Rebound.

Strategic Timing

Because Taigam requires an attack to enable Rebound, you generally want to cast your main-phase sorceries during your post-combat main phase. During your next upkeep, you can stack multiple Rebound triggers in any order you choose. Since they resolve one at a time, remember that you cannot target a later Rebounding spell with an earlier one, as the later one is still in exile.

Interaction examples

Doubling the Lesson

Roaming Throne

With Roaming Throne on the battlefield naming Human or Monk, Taigam's ability triggers an additional time whenever you cast an instant or sorcery from your hand after he has attacked. This results in two Rebound triggers; however, since the first Rebound effect to resolve will exile the spell, the second trigger will typically do nothing as the spell is no longer on the stack to be modified.

Protecting the Board

Solemn Simulacrum

If you cast an instant to protect a creature like Solemn Simulacrum after Taigam has attacked, that spell cannot be countered by your opponents. Once it resolves, it is exiled due to Rebound. At the beginning of your next upkeep, you may cast that protection spell again for free, ensuring your Golem stays safe for another turn cycle.
