Intended for use against aggro decks (just for fun, since I have friends who use Rakdos, Goblin, Exalted-aggro, etc) A mill deck that completely focuses on milling your opponents, using counters and control spells to make sure you stall your opponent's creatures enough to get the mill spells going. Consuming Aberration was the only creature I put in here because of its ability to completely turn the tides in late-game situations, as a sort-of alternate wincon when the graveyard has become 30+.
As this is a control-mill deck, it is imperative that there be 2-3 open mana after every turn (unless necessary), and that there are about 2-4 cards in hand after every turn. The main idea is to control the pace of the game such that it can allow the mill spells to come in and go for the kill whenever possible. This is where draw-advantage cards such as Ponder, Visions of Beyond, or Jace's Ingenuity comes really handy (pun intended hehe).
PREFERRED OPENING HAND: A good opening hand should consist of the following: 3 Lands (preferrably with 1-2 Drowned Catacombs or 1-2 Watery Graves), 2 Early pace-control helpers (Go for the Throat, Counterspell Mana Leak, Propaganda, Ponder), 1 Glimpse the Unthinkable, and 1 Mid-to-late game utility card (Preferrably Black Sun's Zenith, but Mind Funeral or Crypt Incursion would do). Anything less on the first attempt is a reshuffle (in casual play) or a mulligan.
STRATEGY (turn-by-turn reference): By turn 2, the idea is to use Glimpse the Unthinkable to mill the opponent quickly. If not, then the two open mana can always be used to either counter a good spell/early creature or to remove any potential killers. If either is achieved, then for turns 3-4, controlling the pace is the priority. Using the mana to cast spells that either take out their creatures (Go for the Throat for targeting specific creatures that could be harmful), prevent the attacks (Propaganda) as well as counter any more spells they may have against you (Counterspell, Mana Leak). By turn 5, it is ideal to start milling big with mind funeral, again leaving two mana open for more controlling, and by turn 7, the big mill permanents can kick-in (Consuming Aberration, Jace, Memory Adept). Crypt Incursion, as I have found in previous decks of mine is very very handy, since it stalls the game much much longer, giving me a potentially easy way to gain large amounts of life (about 12-18 on average, and 24-above when I've halved the deck of my opponents). Black Sun's Zenith is a personal favorite of mine when it comes to boardwiping because of two reasons: it's very flexible in that you can use it by turn 4 or 5 or even turn 3 for weenies and of course late in the game to wipe out big creatures, and because it's a wallet-friendly card considering its benefits (the fact that it just goes back into your deck is a bonus for me). If the deck survives by turn 8-9, Mind Grind can always come in handy as the finisher. By my experience, Mind Grind has not failed me so far with completely finishing off my opponent. If the game still isn't over by then, there's always Jace, Memory Adept to serve as the safety net and Consuming Aberration to serve as your alternate game-winner.
SIDEBOARD: I've put in Surgical Extraction because in my opinion it is one of the best compliment cards for a mill deck out there. You practically cast it for no mana (especially since i can play Crypt Incursion to shoulder the 2 damage and much much more anyways). Surgical Extraction is good early in the game, in the middle, or even late in the game and it really (from what I've seen so far) throws off your opponent's strategies if you choose the right card - meaning it is also a great sideboard utility card; and can always be interchanged with anything on my sideboard. Leyline of the Void is another important utility card in cade the opponent decides to play anti-mill cards like the classic Elixir of Immortality or anti-mill mechanics like Unearth. Note that to play this card, Crypt Incursion and Consuming Aberration have to be taken out, because Leyline of the Void practically renders them useless.
