This is a rerun of a (not particularly wellreceived, but at least Zya organizes sth at all, which is more than I do) tournament. So for rulequestions I just looked there and can confirm that this was meant to be run with a perfect 50-50 split of elements in decks. Its also worth noting that several people were of the opinion that this could easily be split into 2 tournaments among other possible simplifications.
(also unlike the procedure should be that tourney is still in the archive rather than somewhere you couldnt see it, but contrary to the last posts promise, no decks have been posted in it so its fine anyway)
