Even though it probably would compress the tournament- (set doesnt release until Friday, realistically cant start until Monday?) I think being able to go back and compare PokeBeach's winning deck to the actual World's winner would be kinda fun.
I feel that if you're gonna do Worlds format, do it in August, feels a bit weird playing it after rotation... also I really don't like *this* year's worlds format, too much Zoroark and puzzles. (Voted expanded, which I'm enjoying a lot so far, but we haven't hit rotation yet and who knows how fun standard will be; hopefully it opens things up a bit.)
On a similar note, @PokeMedic is it possible to get metrics on more than just the top 8 decks?
