This shell is in preparation for BNG, and there are several cards in it, of course, that will be cycled out. This is a good shell to train yourself on using the various counter-spells and Cyclonic Drift (which is not coming out for sure). I got me a few cards to boost my blue cards after the ISD block redemptions.
Even though it is a training shell, every now and then this deck can become very powerful: if your opponent allows your devotion to grow, you can be dropping all your fatties and drawing lots of cards. I have even been able to ultimate mill Jace. Aetherling, of course, is your finisher. It is fairly easy to make him an unblockable 8/1.
2/13/2014 update: here is the optimized version. I added Nightveil Specter and took out Divination. This deck is a lot of fun, even if it just a pre-BNG shell, and also a pre-UB shell that will eventually get Ashiok.
Here is yet another optimization.
And here I added Curse of the Swine.
