Can I tap an energy to float 1, then recycle it with a seal to use the 1 floating energy to play a card?

Ruling: Yes, you can exhaust a rune for energy without spending it immediately, then recycle that rune to play a sigil using the floated energy.

Sequence:

• Step one: Exhaust your rune to generate 1 energy
• Step two: Leave that energy in your pool (floating it) instead of spending it immediately
• Step three: Recycle the rune to play a sigil
• Step four: Use the floated energy from step one to pay for the card

Nuances:

• 'Floating' refers to leaving resources in your pool instead of spending them immediately
