This next card is quite possibly the more perfectly designed mill-card that doubles as a utility card, ever produced:
As Blaze is to Lightning Bolt, Increasing Confusion is to Dream Twist... well not exactly. That would be the cast if Dream Twist flashback'd for double the cards. This card on the other hand is just insane. Because of the way the card is designed, it's almost begging for you to hard cast in on yourself and then flashback'd on your opponent. In Innistrad Draft format, this card can almost end the game on its own as efficiently as Devil's Play. I think it's that good.
In my MTG Salvation thread, my force drafting of Mill Strategy in Innistrad for a month has been well documented. And this card is just bonkers for that same strategy. Keep in mind that this is a rare, so it's not like you'll see this card all of the time. But I would even go as so far as to say that if this is easily a pack 1, pick 1 for any Innistrad block draft. And from there, you leave yourself open to either UGb self-mill or the UW or UB offensive mill deck. (Happy drafting!)
