Can you respond to Bullet Time after the player recycles runes to pay power, or does the recycling happen during resolution without opening a response window?

Ruling: You cannot respond to Bullet Time after seeing how much power is paid. The recycling of runes to pay power happens during resolution, and players cannot react during resolution. You must respond to Bullet Time before knowing how much damage it will deal.

Sequence:

• Bullet Time is played and its cost (1 energy) is paid
• Opponents can respond at this point, before resolution
• Bullet Time resolves: player recycles runes to pay power and deals that much damage
• No response window opens during the recycling/power payment

Nuances:

• Bullet Time is templated differently from cards like Falling Star, which use "do this ->" with a colon to create a response window after choices are made
• The power payment is part of the card's effect during resolution, not an additional cost (which would need to be labeled as such or appear in the top left corner)
• This templating is intentional and makes Bullet Time more powerful since opponents must respond without knowing the damage amount
