What it does

As this artifact enters, choose two colors.

Each spell you cast costs 1 less to cast for each of the chosen colors it is.

Rulings

6 official rulings, in the order Wizards published them.

  • 2015-11-04

    If a spell you cast has X in its mana cost, you choose the value of X before calculating the spell's total cost. For example, if that spell's mana cost is X and you've chosen red and green, you could choose 5 as the value of X and pay 3 to cast the spell.

  • 2015-11-04

    If there are additional costs to cast a spell, or if the cost to cast a spell is increased by an effect (such as the one created by Thalia, Guardian of Thraben's ability), apply those increases before applying cost reductions.

  • 2015-11-04

    Seal of the Guildpact's last ability doesn't change the mana cost or mana value of any spell. It changes only the total cost you pay.

  • 2015-11-04

    You must choose two different colors.

  • 2015-11-04

    The cost reduction can apply to alternative costs such as evoke costs.

  • 2015-11-04

    Seal of the Guildpact's last ability can't reduce the amount of colored mana you pay for a spell. It reduces only the generic component of that cost.

Rulings are Wizards of the Coast's own, mirrored from Scryfall and refreshed nightly.

Every version of Seal of the Guildpact

4 printings, newest first. Prices are the market figures Scryfall publishes, refreshed nightly. A printing with no figure shows a dash rather than a zero, because Scryfall publishes none for some of them.

Prices from Scryfall, which tracks the TCGplayer and Cardmarket markets. They move daily and are a guide rather than a quote. Search TCGplayer for Seal of the Guildpact. It runs a name search across every version, which covers the printings TCGplayer publishes no direct link to.

Aggregated from Commander games tracked in TurnZero HQ. Every figure counts decks and games only. No individual deck list, player or playgroup is identified. Win rates are withheld below 5 completed games, where the sample is too small to mean anything.
