My friends have been developing a deck similar to this couple of months already. The main difference is that we play lone ETW as the only win condition main deck and opt for more draw in form of Fact and Twister instead. The philosophy behind our deck is to run as few blanks as possible. This has an edge against GAT because it has the same engine and same disruption, but it draws into real business when GAT draws into green and filler cards.
We have tried to make creator of the deck to make a thread about it here, but he felt his English is too poor or had some other lousy explanations. Hope he'll finally open his mouth here.
I've also found the draw7s to be the nut high when you're running gush and fastbond. You're much, much less likely to pass the turn after a wheel with a gush deck than you are in, say, pitch long. You're also running duress, hedging against handing your opponent the nuts when you can't pull it out, and that makes a huge difference. My list does include 2 rituals, but they don't show up enough for me to factor that in at all.
