Can you float power by recycling runes at any time, even if you don't immediately use it?

Ruling: Yes, you can float power by recycling runes at any time you have priority or when spending a resource for an effect/card, even if you don't immediately use it. Runes have activated abilities that work like any other activated ability and don't require you to be paying costs to activate them.

Nuances:

• Any resources in your rune pool will be lost when you get to the draw phase
• Players should track floated resources carefully using methods like: flipping recycled runes face-up on top of the rune deck, using dice for longer-term floating, or using pen and paper at higher levels of play
• Common use case is floating energy and power before playing Divine Judgment, using the floated power to hide cards before casting the spell
