Can my opponent float their resources (energy and power) as a reaction to Divine Judgement?

Ruling: Yes, your opponent can float resources as a reaction to Divine Judgement. Runes have "Exhaust - Reaction: Add 1 Energy" and can be activated before the spell resolves. They can also recycle runes to float power.

Sequence:

• When Divine Judgement is played, the opponent has priority before it resolves
• The opponent can exhaust runes to add energy (one at a time technically, but can be shortcut)
• The opponent can also recycle runes to add power
• All floated resources will be lost when the turn ends
• Divine Judgement then resolves, reducing runes to 2

Nuances:

• Abilities that "Add" resources cannot be responded to, even with other "Add" abilities, so they technically resolve one at a time, though shortcutting is acceptable
• Recycling runes while floating can trigger effects like Sivir's legend ability to create Gold tokens
• Gold tokens created this way come in tapped, so typically can't be used same turn
• Floating resources is useful to have energy/power available until end of turn after Divine Judgement resolves
