Can you exhaust all 12 runes to create a pool of 12 floating energy, then cast Divine Judgment and have 5 floating energy remaining to use during that turn?

Ruling: Yes, you can exhaust runes at any time to generate energy and create a floating pool of resources. Both players can exhaust and recycle their runes in response to Divine Judgment, and you can float both energy and power.

Sequence:

• Exhaust runes to generate energy (creating a floating pool)
• Recycle runes to generate power (creating a floating pool)
• Pay the cost of Divine Judgment from your floating resources
• Use remaining floating resources during that turn
• Floating resources are lost at end of turn and end of draw phase

Nuances:

• You cannot exhaust or recycle runes without generating the respective resource - these are limited actions that can only be performed when activating the rune's abilities
• Runes have implicit "Reaction - Exhaust me: get 1 energy" and "Reaction - recycle me: get 1 power" abilities
• Both players can float resources before Divine Judgment resolves
• There is no downside to floating all available resources before Divine Judgment, even if you don't intend to use them all
