For Bullet Time, do you recycle runes as a cost when playing the card (before opponent responds), or do you play it first, let opponent respond, then pay the power cost afterwards?

Ruling: You play Bullet Time first, your opponent responds without knowing how many runes you'll spend, then after their response resolves you choose how much power to pay by recycling runes.

Sequence:

• Play Bullet Time
• Opponent makes any responses they want (without knowing how much power you'll spend)
• Opponent's responses resolve
• You choose how much power to pay by recycling runes and Bullet Time resolves

Nuances:

• You pay power by recycling runes, not "pay runes" directly
