Nvm, thanks Aves for the quick answer. I just cant read properly, the other question I asked I could answer with the information in the OP as well.
The info being revealed after the end of the NEXT deckbuilding phase seems a bit odd, it would seem more appropriate to reveal it at the start of next deckbuilding phase. There is a good chance that there is only 2 competitive teams left at all in round 13, so its hard to imagine the information being used much.
Several Edits later:
It's too late for me, I ask a lot of unnecessary questions. The results cannot be posted any sooner, as there is no information on it yet, silly me. So the only critique remaining is that it helps only the teams that can expect to make it far at all and it isn't very useful in general (By using it on the previous rounds decks it could be a little more useful, but I'm not sure whether its worth changing the card). And thats fine, we've had worse.
