Forum:Pyro clock of destiny???

How exactly does pyro clock of destiny work??? can I use it as a combo for wave motion cannon? Like if I played wave motion cannon and it is already my 2nd standby phase after I activated wave motion cannon, can I activate pyro clock of destiny so that it can have 2 counters already?? Is that right? And can I use pyro clock of destiny to counter change of heart? Because change of heart controls a monster for 1 turn only, so if i activate pyro clock of destiny will the control of the monster be mine already? Is that how to use it?
