Carte Magic Agatha's Soul Cauldron

Agatha's Soul Cauldron 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

You may spend mana as though it were mana of any color to activate abilities of creatures you control. Creatures you control with +1/+1 counters on them have all activated abilities of all creature cards exiled with Agatha's Soul Cauldron. {T}: Exile target card from a graveyard. When a creature card is exiled this way, put a +1/+1 counter on target creature you control.

Complete guide

Agatha's Soul Cauldron is a versatile legendary artifact that turns your graveyard into a toolbox for your creatures. By exiling fallen heroes, you can grant their unique talents to anyone on your battlefield who carries a +1/+1 counter. This card bridges the gap between resource management and explosive creature synergies.

What It Does

Agatha's Soul Cauldron has three primary effects. First, it allows you to spend mana as though it were any color to activate creature abilities, ensuring you are never color-screwed when using borrowed powers. Second, it grants every creature you control with a +1/+1 counter all activated abilities of creature cards currently exiled by the Cauldron. Finally, it provides a repeatable way to exile cards from graveyards while distributing +1/+1 counters to fuel its own requirement.

How It Resolves Step by Step

When you tap the Cauldron, you target a card in any graveyard. As the ability resolves, that card is exiled. If the card was a creature card, you then choose a target creature you control to receive a +1/+1 counter. Once a creature card is in exile under the Cauldron, the static ability immediately begins applying to your creatures that have +1/+1 counters. They gain those abilities as if they were printed on them, meaning if an ability refers to the card's name, it now refers to the creature that gained the ability.

Common Mistakes

A frequent error is trying to inherit triggered abilities (which start with 'When', 'Whenever', or 'At') or static abilities (like Flying or Trample). The Cauldron only grants activated abilities, which are formatted as '[Cost]: [Effect]'. Additionally, remember that if the Cauldron leaves the battlefield, your creatures lose all the abilities it was providing, even if they still have their +1/+1 counters, because the granting effect is tied to the artifact itself.

When to Play It

This artifact is best utilized in decks that can easily generate +1/+1 counters or those that rely on specific creature-based combos. It serves as excellent graveyard hate against opponents while simultaneously buffing your board. Because it allows mana fixing for activations, you can even include powerful off-color activated abilities in your deck just to exile them and use them via the Cauldron.

Interaction examples

Fueling the Cauldron

While Sol Ring and Arcane Signet are artifacts and cannot be exiled by the Cauldron to grant abilities (as the Cauldron only grants abilities from exiled creature cards), you can use the mana generated by Sol Ring and Arcane Signet to pay for the activated abilities your creatures have gained. The Cauldron's first ability ensures that even the colorless mana from Sol Ring or specific colors from the Signet can be spent as any color for these activations.

Building a Super-Creature

If you use Agatha's Soul Cauldron to exile a creature with '{T}: Add {G}', every creature you control with a +1/+1 counter can now tap for green mana. If you later exile a second creature with '{2}: Draw a card', those same creatures now have both the mana-tapping ability and the card-draw ability. This allows a single creature to accumulate a massive list of options.

How it works : Agatha's Soul Cauldron

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    Activated abilities contain a colon. They're generally written "[Cost]: [Effect]." Some keyword abilities are activated abilities and will have colons in their reminder text.

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    Agatha's Soul Cauldron grants only activated abilities. It doesn't grant keyword abilities (unless those keyword abilities are activated), triggered abilities, or static abilities.

    No other card is named in this ruling.

  3. #3· Wizards of the Coast

    The granted abilities effectively use "this permanent" rather than "[that card's name]," so you treat the abilities as though they were printed on the creature that gained the ability. For example, say you exiled the card Argothian Sprite with Agatha's Soul Cauldron. Argothian Sprite has the ability "{7}: Put two +1/+1 counters on Argothian Sprite." If you controlled a Callous Sell-Sword with a +1/+1 counter on it, you'd treat it as though it had the ability "{7}: Put two +1/+1 counters on Callous Sell-Sword."

    No other card is named in this ruling.
