Can you use Seals to pay for themselves?

Ruling: You cannot use a Seal you are trying to play to pay for itself, because you pay costs before the card enters play. However, you can use a Seal already in play to pay for a second Seal, as long as it matches the correct domain (color).

Sequence:

• Pay costs for the card (including using Seals already in play)
• The card enters play

Nuances:

• A Seal already in play can pay for another Seal being played if it's the correct domain
• A Seal cannot pay for its own cost since it's not in play yet when costs are paid
