darkrai/partner(s) should be on the list they will be very popular decks they are worth testing against/gathering data on them.
and btw i think this data will only show what tourney results will probably be like and not a comparison on how decks fair against each other...
because to test how a deck fairs against another one they have to be piloted by players of same skill(pros) and each have a perfected deck list(much testing and adjustments)
but in tournaments much like from this data, its random. so you can get a lil taste of what the tourney results are gonna be.
