Considering I may actually make this one, here I post.
I agree with the initial decision to send decks per pm to the TOs rather than posting them openly, I find it changes and influences the strategical plannig for the entire event more, whereas public posting narrows it down for the coming matches, especially the later ones, at least regarding elemental combos, those can show a lot already, knowing if the opponent still has PC/CC available can be game changing.
The downside is of course that not much prevents the ones who lost to say what combos they lost to.
Nice tourney, hope I'll make it.
