Ruling Lost World

[Celebi23]

If I have Lost World in play and then put my opponent's 6th Pokemon into the Lost Zone via an attack (like Hurl Into Darkness or Sleepy Lost), do I get to win the game after that attack or do I have to wait until my next turn?

You know, now that I read the text, you have me questioning my TO who told me the ruling I mentioned in that post. I retract my earlier statement and will say this: You have to wait until your next turn to play or use the stadium to win the match if you choose to.

From the Compendium:
Q. If my opponent has 6 or more Pokemon cards in his or her Lost Zone after my Pokemon uses its attack, but prior to the start of my opponent's turn, can I declare myself the winner with the effect of the "Lost World" Stadium?
A. No, you can't. You can only declare victory with the effect of Lost World prior to your Pokemon using an attack. Once you begin your attack, you cannot use Lost World's effect. (Call of Legends FAQ; Feb 10, 2011 PUI Rules Team)

...basically you have to declare Lost World's effect during the "Main Phase". By definition, when you attack, you finish the attack completely, and then your turn is immediately over.
