I suppose no one was in/cares about Phillidelphia. We're missing 10 decks from the T8 already. I could compile a T16 and T32 as best as possible, but we will be missing a lot of decks.
Either way, I will get to compiling a list of the T32 in masters in a day or so. If anyone does have any info on Philly then that would be greatly appreciated.
edit: Updated with a complete T32 from what has been posted. Missing 51 decks, but there's still a pretty comprehensive picture of the Regionals metagame in the summary.
