Can you float energy from runes (tap a rune for energy, recycle it, then use that energy later in the same turn)?
Ruling: Yes, you can float energy from runes. You can tap a rune to generate energy, recycle that rune (e.g., with Seal of Unity), and then use the previously generated energy later in the same turn to pay for other cards.
Sequence:
- Tap a rune to generate 1 energy
- Play Seal of Unity, recycling the tapped rune
- Use the floating energy (from the recycled rune) plus energy from other sources to pay for a card
Nuances:
- Your pool of energy and power only empties at the end of the draw phase and at end of turn
