Can't wait to see how viable a Red/Blue Flashback based deck is. I beleive theres a card that does damage when a flashback spell is cast, so with that new awesome card I can see tons of mayhem occuring. It's been awhile since I've had a red/blue deck, the time is right. http://mtgsalvation.com/dark-ascension-spoiler.html
Edit
I just seen increasing confusion, a deck that mills yourself to death with Labratory Maniac is now actually feasable. Good god, the horrors! Hahahah, I'm loving this set.

Just seen Mondronen, so with the one card doing damage on flashback spells. And him doing damage because of being transformed you get a pretty powerful combo going. You would need some way to work out the transformation and get it to stick. Anad I know how, Phantasmal Illusion. So then you dont have to worry about about him being transformed. Then with an illusion lord you have hexproof I beleive? Holy good god, that's going to be a pretty powerful deck if it works out like I'm thinking.

I was dubious of this set, but seeing those cards. I've got a MUST BUY on a booster box on release day.
