Can a player float energy from runes before recycling one for a Seal's power cost, and can a Seal pay for itself?

Ruling: You can exhaust runes to float energy before recycling a rune to pay for a Seal's power cost. A Seal cannot pay for itself, but one Seal can pay for another Seal.

Sequence:

• Exhaust runes to float energy before paying costs
• Recycle one rune to pay for the Seal's power cost
• The Seal enters play ready and can be used the same turn
• Use the floated energy and additional runes to pay for other cards

Nuances:

• Seals have an energy cost of 0 but require 1 power (paid by recycling a rune)
• A Seal cannot pay for its own power cost
• One Seal can pay for another Seal's power cost
