I heard this was gonna be the next event, so I guess I'll give my 'way late' feedback.
First of all, SoGs were bad for this event. You either had to play them or play a deck to counter them. With the nerf, they may not be as bad, but I doubt you'll allow any Shards yet.
Second, if a player gets a bye, as Napalm said, they should have to post their deck. The bye is already enough of an advantage.
Third, I like the 6 upped cards rule, I'm pretty sure others did as well, but I don't think they should be 'set' from the start. You should be able to pick to upgrade any 6 cards in your deck that you want. This will give even more teching if necessary.
Other than that, I think the event can be left how it is.
(Also, I can host if you still need someone.. but people would have to send their decks to you, since that'd be too much of an advantage if I saw everyone's decks.
