Well, the idea is to get a second chance and a Hanna on the table, and then take infinite turns by lowering yourself to 5 life with either necropotence or lim-dul's vault. Eventually, you'll have enough mana to either kill with the morphling or the urza's rage. The diggers make sure you never run out of cards to draw. =] It actually works surprisingly well, but comments would be appreciated. =]
I've been working on a deck that abuses Second Chance for a while. Instead of using Hanna, try Replenish. It's about 1,000 times better.
I also have Sylvan Library instead of Necro and some Pursuit of Knowledge as icing on the Replenish cake.
