Can Seals allow you to play a card without having enough runes to tap for its Energy cost, and can you float Energy/Power between actions?

Ruling: Players can float Energy and Power between actions. Seals provide Power but not Energy, so you still need enough runes to exhaust for the Energy cost before recycling runes to pay for the Seal.

Sequence:

• Exhaust runes for Energy (e.g., 4 runes for Sona's Energy cost)
• Recycle a rune to pay for the Seal cost
• Play the Seal
• Tap the Seal for Power
• Play the card (e.g., Sona)

Nuances:

• The ability to float Energy/Power is not unique to Seals; it's a general game mechanic
• Multiple sequencing orders may be valid as long as Energy is generated before runes are recycled
