Creature - Illusion 3/3, 3U (4) Flying Vanishing 3 (This permanent enters the battlefield with three time counters on it. At the beginning of your upkeep, remove a time counter from it. When the last is removed, sacrifice it.) When Chronozoa is put into a graveyard from the battlefield, if it had no time counters on it, put two tokens that are copies of it onto the battlefield.1

2/1/2007: The ability checks to see if Chronozoa had no time counters on it at the time it was put into a graveyard from the battlefield. This doesn't necessarily mean it must have been sacrificed due to vanishing; it could have been put into the graveyard some other way (say, while the sacrifice ability of vanishing is on the stack).
2/1/2007: Chronozoa's last ability creates two Chronozoa tokens that each enter the battlefield with three time counters and have all of Chronozoa's abilities.
2/1/2007: If Chronozoa becomes a copy of another creature and is put into the graveyard from the battlefield, no copies will be created. If another creature becomes a copy of Chronozoa and is put into a graveyard from the battlefield (with no time counters on it), two copies of Chronozoa will be created.
