Carte Magic Agate Instigator

Agate Instigator 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.

01

Official card text

Offspring {1}{R} (You may pay an additional {1}{R} as you cast this spell. If you do, when this creature enters, create a 1/1 token copy of it.) Whenever another creature you control enters, this creature deals 1 damage to each opponent.

Complete guide

Agate Instigator is a low-cost Lizard Rogue that punishes your opponents every time you expand your board. By utilizing the new Offspring mechanic, you can double your impact and turn every subsequent creature entry into a barrage of damage.

Understanding Offspring

Offspring is an optional additional cost you pay while casting the spell. If you pay the extra {1}{R} for Agate Instigator, a triggered ability goes on the stack once the original creature enters the battlefield. When this ability resolves, you create a 1/1 token copy of Agate Instigator. This token possesses the same 'ping' ability as the original, meaning you now have two sources of damage for every creature that follows.

Resolving the Damage Trigger

The core ability triggers whenever another creature you control enters the battlefield. Note that the original Agate Instigator does not trigger for itself. However, if you paid the Offspring cost, the 1/1 token copy is considered 'another creature' relative to the original. This means when the token enters, the original Agate Instigator will deal 1 damage to each opponent. Once both are on the field, every new creature you play will trigger both lizards, dealing a total of 2 damage to each opponent.

Common Mistakes

A common misconception is that the token is 'cast'—it is not. The token is created by a triggered ability, so effects that care about casting spells won't see the token. Additionally, you can only pay the Offspring cost once per spell; you cannot pay it multiple times to create a swarm of lizards. Finally, if Agate Instigator is countered, the Offspring ability never triggers, and you won't get the token.

Strategic Timing

Agate Instigator is most effective in decks that generate multiple creatures in a single turn. Since it hits 'each opponent,' it is particularly potent in multiplayer formats like Commander. To maximize value, play Agate Instigator early with its Offspring cost so that every utility creature or token generator played later in the game contributes to lowering your opponents' life totals.

Interaction examples

Self-Triggering with Offspring

You cast Agate Instigator and pay the additional {1}{R} for Offspring. The original Agate Instigator enters the battlefield. This puts the Offspring trigger on the stack. When the trigger resolves, a 1/1 token copy of Agate Instigator enters. Because the token is 'another creature' entering under your control, the original Agate Instigator's ability triggers, dealing 1 damage to each opponent.

Scaling Damage

With an Agate Instigator and its 1/1 Offspring token already on the battlefield, you cast Ornithopter of Paradise. When Ornithopter of Paradise enters, both Agate Instigator permanents see it. Each one triggers separately, dealing 1 damage to each opponent for a total of 2 damage.

Synergy with Treasure Generation

You have Agate Instigator on the field and cast Professional Face-Breaker. When Professional Face-Breaker enters, Agate Instigator deals 1 damage to your opponent. Later, if you attack and deal damage, Professional Face-Breaker creates a Treasure. Note that creating the Treasure does not trigger the Instigator, as the Treasure is not a creature, but the initial entry of the Face-Breaker provided that crucial guaranteed damage.

How it works : Agate Instigator

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    You can pay an offspring cost only once as you cast a spell with offspring. You can't try to pay it multiple times to get more token copies.

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    If the spell is countered, the offspring ability will not trigger, and no token will be created.

    No other card is named in this ruling.

  3. #3· Wizards of the Coast

    If the spell resolves but the creature with offspring leaves the battlefield before the offspring ability resolves, you'll still create a token copy of it.

    No other card is named in this ruling.

  4. #4· Wizards of the Coast

    The token copies exactly what was printed on the original creature and nothing else, except it's a 1/1 (unless that creature is copying something else; see below). It doesn't copy whether that creature is tapped or untapped, whether it has any counters on it or Auras and Equipment attached to it, or any non-copy effects that have changed its types, color, or so on.

    No other card is named in this ruling.

  5. #5· Wizards of the Coast

    In the rare case where the original creature is copying something else when the offspring ability resolves, the token enters as whatever that creature copied, except it's a 1/1.

    No other card is named in this ruling.

  6. #6· Wizards of the Coast

    Many creatures with offspring abilities have other abilities that refer to them as "this creature" rather than referring to them by name. This difference is for clarity purposes and does not change the function of any of these abilities.

    No other card is named in this ruling.

  7. #7· Wizards of the Coast

    Any "enters" abilities of the copied creature will trigger when the token enters. Any "as [this creature] enters" or "[this creature] enters with" abilities of the copied creature will also work.

    No other card is named in this ruling.

  8. #8· Wizards of the Coast

    The token created by the offspring ability isn't "cast", so abilities that trigger when a creature spell is cast won't trigger for the copy.

    No other card is named in this ruling.

  9. #9· Wizards of the Coast

    In the rare case where the creature doesn't have the offspring ability when it enters, the ability won't trigger even if you paid the offspring cost.

    No other card is named in this ruling.
