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

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.

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.

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