Forum:Pyro Clock of Destiny question

Does Pyro Clock of Destiny effect all cards that are counting turns or do you have to designate just one card (or card effect) to use it on? I had always thought it effected all cards until I read it's ruling on Final Countdown:
 * When you activate Final Countdown, and your opponent activates Final Countdown during his next turn, and then uses Pyro Clock of Destiny to advance his/her Final Countdown by 1, both Final Countdowns win at the same time and the Duel is a Draw.

If it did effect all card effects wouldn't your opponent activating Pyro Clock of Destiny forward your Final Countdown also?--DarkMastero 16:54, 7 February 2008 (UTC)
