Can I defy Bullet Time if he pays 6 power?
No, you cannot Defy a Bullet Time after the opponent has already paid 6 power for it.
According to RiftJudge FAQ #4175:
- Ruling: You cannot Defy a Bullet Time after the opponent has paid power for it. Paying power is part of Bullet Time's effect, and once the power is paid, it is too late to Defy.
Why this is the case:
- Timing: Bullet Time must be Defied while it is on the chain, before the opponent pays any power. The payment of power happens during the resolution of the spell, not when it is played.
- Response Window: Players must provide a response window after playing Bullet Time but before they specify or pay any power. If your opponent has already paid the 6 power, they have moved past the window where you could have responded with Defy.
- Cost Checking: While Defy can target Bullet Time (because it checks the card's printed cost, not the amount of power paid during resolution), it must be played while the spell is still on the chain waiting to resolve. Once the resolution process begins and the power is paid, the opportunity to counter the spell has passed.
