I bet you that there's a 95% chance that they'll be using a Earth-Light duo stall against us, with Holy Flashes for added insult (to either damage our creatures or to heal themselves because they're so cheap). Hell, even a mono-light stall can still screw us over if they have the quanta generation going.
But aside from that, I wouldn't question their strategy of using a Divine Glory deck against us, with Deflag (if xdude is using the deck for free Animated Weapons) to remove Dusk Shield and the like so we can't avoid some of the damage.
Do you think they'll be using Hope against us?
