Emeritus of Abundance // Regrowth — ruling 1

While copies of spells in zones other than the stack cease to exist when state-based actions are checked, this does not apply to copies of prepare spells in exile that were created as a creature became prepared.

Emeritus of Abundance // Regrowth — ruling 2

If a prepare spell with one or more targets has no legal targets when it tries to resolve, it won't resolve and none of its effects will happen. Since the spell was cast, the associated permanent will still not be prepared.

Emeritus of Abundance // Regrowth — ruling 3

Only the current controller of a prepared creature can cast the copy of its prepare spell in exile. It doesn't matter who owns that creature or who controlled it when it became prepared.

Emeritus of Abundance // Regrowth — ruling 4

Creating a copy of a creature's prepare spell in exile ignores copy exceptions applied to that creature that would affect the copiable values of that spell. For example, say a player casts Croaking Counterpart (a sorcery that says "Create a token that's a copy of target non-Frog creature, except it's a 1/1 green Frog.") targeting Goblin Glasswright. The token copy of Goblin Glasswright will enter prepared as a 1/1 green Frog creature, but the copy of Craft with Pride in exile will still be a red sorcery. The copy of Craft with Pride won't be green, a creature, or a Frog, and it won't have power or toughness.

Emeritus of Abundance // Regrowth — ruling 5

Being prepared isn't a copiable value. If a permanent becomes a copy of a prepared creature, it won't be prepared. That permanent will have the alternative characteristics, though, and some other effect could cause it to become prepared later.

Emeritus of Abundance // Regrowth — ruling 6

As an effect causes a creature with a prepare spell to become prepared (including effects that state that a creature "enters prepared"), that creature's controller creates a copy of that creature's prepare spell in exile. That copy remains in exile for as long as that permanent is on the battlefield and is prepared. That creature's controller may cast that copy as long as it remains in exile. As they cast it, that creature stops being prepared.

Emeritus of Abundance // Regrowth — ruling 7

Casting a copy of a prepare spell from exile isn't casting it for an alternative cost. Effects that allow you to cast a spell for an alternative cost or without paying its mana cost may allow you to apply those to a copy of a prepare spell cast from exile.

Emeritus of Abundance // Regrowth — ruling 8

If a prepared creature loses all abilities, it won't stop being prepared, and nothing will happen to its alternative characteristics or to the copy of its prepare spell in exile.

Emeritus of Abundance // Regrowth : règles, fonctionnement et interactions (MTG)

Emeritus of Abundance // Regrowth 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

Vigilance This creature enters prepared. Whenever this creature attacks, if you control eight or more lands, this creature becomes prepared. Return target card from your graveyard to your hand.

Complete guide

Emeritus of Abundance is a powerful Elf Druid that bridges the gap between creature-heavy strategies and spell-based utility. By using the new 'prepared' mechanic, this creature allows you to access a Regrowth spell directly from exile, ensuring your graveyard is never out of reach.

What it Means to be Prepared

Emeritus of Abundance enters the battlefield 'prepared.' This means its controller creates a copy of its associated prepare spell, Regrowth, in exile. This copy stays in exile as long as the Emeritus is on the battlefield and remains prepared. You can cast this copy from exile by paying its mana cost of {1}{G}. Once you cast the Regrowth copy, the Emeritus stops being prepared. To prepare it again, you must attack with it while controlling eight or more lands.

Resolving the Preparation Step by Step

When Emeritus of Abundance enters the battlefield or its attack trigger resolves, the 'become prepared' effect happens. First, the game checks if the creature is already prepared; a creature cannot be prepared twice. If it isn't, you create a copy of the Regrowth spell in exile. This is a copy of a spell, not a card, but it follows the rules of the Regrowth spell's characteristics. You may cast it any time you could normally cast a sorcery. If you cast it, you follow all normal targeting rules. If the spell is countered or fails to resolve due to illegal targets, the creature still loses its prepared status because the spell was cast.

Common Mistakes and Misunderstandings

A common error is trying to cast Regrowth as a card from your hand; you can only cast the creature side from your hand. Additionally, the attack trigger has an 'intervening if' clause. This means the game checks if you have eight lands at the moment you declare attackers AND at the moment the trigger tries to resolve. If you lose a land in response to the trigger, the Emeritus will not become prepared. Finally, remember that if the creature leaves the battlefield, the copy of Regrowth in exile ceases to exist.

When to Play Emeritus of Abundance

Early in the game, it serves as a 3-mana Vigilance creature that grants you immediate access to a Regrowth to pick up a fetch land or a discarded threat. In the late game, it becomes a repeatable engine. Once you hit eight lands, every attack refreshes your ability to pull cards from your graveyard, making it an inevitable source of card advantage in long matches.

Interaction examples

Ramping into Renewal

Solemn Simulacrum

You have seven lands and a Solemn Simulacrum in your graveyard. You cast Emeritus of Abundance, and it enters prepared. You immediately cast the Regrowth copy from exile, targeting Solemn Simulacrum to return it to your hand. Now you can replay the Golem to find your eighth land, ensuring that the next time Emeritus of Abundance attacks, it will trigger to become prepared again.

Instant Speed Land Sacrifice

Sakura-Tribe Elder

You control seven lands and a Sakura-Tribe Elder. You attack with Emeritus of Abundance. Because you only have seven lands, the 'if you control eight or more lands' ability does not trigger. You cannot sacrifice the Sakura-Tribe Elder after declaring attackers to try and trigger the ability, as the condition must be met at the exact start of the Declare Attackers step.

As they cast it, that creature stops being prepared.

Emeritus of Abundance's last ability checks at the moment it would trigger to see if you control eight or more lands. If you don't, the ability won't trigger at all. It's not possible to put lands onto the battlefield during your declare attackers step in time to have the ability trigger. If it does trigger, the ability will check again as it tries to resolve. If you don't control eight or more lands at that time, the ability won't resolve and none of its effects will happen.

#11March 20, 2026· Wizards of the Coast
A creature with a prepare spell can't become prepared more than once at the same time. For example, Emeritus of Ideation is on the battlefield and is prepared. When it attacks, its last ability triggers. When that ability resolves, its controller may still exile eight cards from their graveyard, but doing so won't cause Emeritus of Ideation to become prepared a second time or create a second copy of Ancestral Recall in exile.
