Does the blue seal (Sapphire Seal) provide energy or just power, and how can a player use it to pay for Teemo after channeling runes?

Ruling: The Sapphire Seal only provides power, not energy. The player was able to pay for Teemo by floating energy from a rune they recycled earlier to pay for the Seal, then using that floated energy along with the Seal's power.

Sequence:

• Player channels two runes (adding energy to their rune pool)
• Player plays Sapphire Seal for one power, exhausting one rune (the energy from this rune goes into the rune pool)
• Player plays Teemo using the floated energy from the rune pool plus the power from the Seal and the remaining physical rune

Nuances:

• The rune pool (where energy floats) and physical runes are separate concepts
• Energy from recycled/exhausted runes remains available in the rune pool even after the physical rune is used
