When recycling an active rune as a cost for conquering Sigil of the Storm, can you keep the floating energy from that rune?

Ruling: Yes, you can keep the energy. You tap the rune first to add its energy to your pool, then recycle the rune to pay the conquest cost. The energy remains in your pool until end of turn.

Sequence:

• Tap the active rune to add energy to your pool (this is a reaction that cannot be responded to)
• Recycle that rune to pay the conquest cost
• Use the floated energy before your turn ends (it disappears at end of turn)

Nuances:

• Energy produced from a rune is not attached to the rune that produced it
• You can tap runes at any time for any reason to float energy
• Floated energy disappears when your turn ends, so you cannot save it for the opponent's turn
• Tapping a rune is a reaction ability that cannot be reacted to (like all abilities that "add")
