Can you recycle runes at reaction speed to float power in response to an opponent's action?

Ruling: Yes, you can recycle runes at reaction speed to float power because the rune itself has the ability to be recycled, which creates the limited action.

Sequence:

• Opponent plays an action (e.g., Divine Judgement)
• In response, you can recycle runes to float power
• You retain both the floated energy and power in your rune pool

Nuances:

• A card must specifically instruct you to recycle it; you cannot recycle cards at will without an ability that allows it
• The rune's own ability is what makes recycling it a limited action that can be performed at reaction speed
• This interaction can be used to trigger abilities that care about recycling runes (like Sivir's legend ability), though such abilities may have their own restrictions like requiring exhaust
