Prismatic Milling - Possible?

I want to try out Prismatic kind of seriously, and I was wondering if one of my favorite deck styles is even possible. What would I need to make a good mill deck for prismatic?
MaGo had one, a long time ago.

I'd say it would be possible, though probably not very good. Still, Traumatize followed by Haunting Echoes is fun times. Echoes is kinda expensive for the effect though (moneywise)
