Although I see a number of decks posted that have most of the cards that this deck has, it is really all about getting the cards to work together. Initially, I put this together only to comment on another deck, but it seems to have grown into something that I may actually take to an FNM. I like it, and it should be fun to play.
The concept is simple. If you have 2 Psychic Corrosion and 1 Fraying Sanity on the field (or 1 Psychic Corrosion and 2 Fraying Sanity), you effectively mill 8 cards for each card that you draw. The object is to set up the board to that condition as quickly as possible, then draw 6 or 7 cards in a turn for a Slam Dunk.
To get there, use Nissa, Steward of Elements, Rashmi, Eternities Crafter and Tatyova, Benthic Druid to keep cards flowing from your library. With Wayward Swordtooth on the field, you get to play surplus lands in your hand. Reliquary Tower allows you to keep a large hand. Once you have 6 or 7 lands on the field, 3 of your mill enchantments and Tatyova, Benthic Druid on the field at the same time, cast Scapeshift for the Slam Dunk
Llanowar Elves provides some useful early mana ramp.
Broken Bond mainly for protection against vehicles.
Negate and Syncopate can counter some of your opponent's control.
Heroic Intervention provides some protection for your creatures.
