I thought your prophecy is about team holding the first position in the last round.
No, I said
will have most of its wins during round 7 (that means that if we lose 0-5 every round but we get 1-5 during round 7, the prophecy will be fulfilled), the 1st place is not needed for the prophecy to be proven at all (but it will still be really helpful).
EDIT: This www3's comment may help Wyand and others to better understand my prophecy:
Inb4 light wins only one match during whole of war, and that’s in r7
In other words, I want Light to win War but it is not mandatory for the prophecy to come true...
