[DECK] Lich in Legacy?? You're nut. (prototype)

Deck Summary:
The challenge here is to make a crazy combo (Lich/Mirror Universe) viable in Legacy. This will never win a tournament, but the objective is to win some games with something original (may I even venture "bold"..?)

Apart from the combo (with honest mana or Academy Rector gets Lich and Delaying Shield out, Copper Gnomes get the Mirror out), you have a somewhat fast/versatile landbase, some Lich side-effect protection (Gravecrawler interacting with the Scullers, ready for sac and re-sac vs. small beaters), Tutors and an alternative win condition (Death's Shadow).

I couldn't resist putting the Academy Rector into Diabolic Intent combo in there for Omniscience/Enter the Infinite and instant win condition with Lich and Repay in Kind. I know it is silly. There were 2 Lotus Petal in there originally instead.

The land base is what I have/can afford. Of course 4 Scrubland would be better, but let's think semi-"limited budget" here.

The whole thing is just a prototype right now, criticisms and suggestions welcomed.
Especially if you think of an helpful card I haven't considered yet.
(And yes, I know that you can't "pay 2 life" for Godless Shrine once Lich is in)
