Token producing deck currently primed for after M13 but pre-rotation (though it can easily be made into a post rotation but substituting Index in for Ponder.
This is still a prototype, but I see tokens being a pretty impressive deck once rotation hits.
So the choices so far seem clear.
Lingering Souls and Intangible Virtue were banned in block constructed for a reason. They're just that good together and by themselves.
Midnight Haunting - this works well to surprise your opponent with two flying tokens on their turn. Its even more surprising when you flash out a snapcaster mage and flash this back on their turn. One intangible virtue on the field and that becomes a 6 power swing.
Gather the Townsfolk - for 2 mana you get 2 1/1 creatures and if you happen to be down and out you get 5 of them. Again an intangible virtue on the field and life is good.
Sorin, Lord of Innistrad - You might be thinking isn't 4 a little excessive. You may be right, but his emblems never go away and his 1/1 lifelink vampires are a pain to deal with especially when you have an emblem and a Intangible Virtue. Sorin wins games without ever getting to his ultimate.
Snapcaster Mage - flashback for Gather the Townsfolk and Midnight Haunting is pretty sweet.
Delver of Secrets
- When you're running 22 instants and sorceries he just makes a great addition in general.
Sign in Blood - This deck needs card draw to be able to be sustainable and this is a fast and efficient way to do it. (though its mana cost may be prohibitive)
Divine Deflection - does double duty and can be pretty efficient in general.
Entreat the Angels - This card wins games in non-token producing decks. In this deck, let's just say that it will make everyone's life difficult.
Suggestions are welcome. Still working to finish it off.
