Update: After going from Rank 20 to Rank 8 in 2-3 days (2'ish hours a day. 5-6 game winstreaks standard) with this deck, I'm finding more success with Water Elemental instead of Eater of Secrets (The hunter secret meta is overrated, imo). Helps to have another solid minion in all matchups, rather than relying on a secret meta.

I've been having tremendous success with this decklist.

The power of this deck comes from the multitude of 1 drops. Arcane Anomaly was the key that Tempo Mage needed to really rev up. Now you have a much greater chance of mulliganing a 1 drop, followed by a beautiful curve. 2 mana - Cult Sorcerer or Sorc. Apprentice, followed by Arcane Intellect or Flamewaker, into a (discounted) Cabalist's Tomb/Ethereal Conjurer.  The problem for opponents is that they frequently use their removal spells on your Mana Wyrms/Arcane Anomaly, and end up leaving your 2 drops alive.

Against control, you can use Conjurer and Tombs todraw Polymporphs/Flame Lance, and Firelands Portal is incredible at taking out Fire Elemental size minions (or the other staple 5 health drops in midrange, control. It'll be tremendous once the 6 mana 5/5 Copy Beast Druid card is released too). Portal frequently puts amazing minions into play, and I've gotten Leeroy Jenkins (5+6=11 to the face) and Nexus Champ Saraad a fair share of times.

Against Agro, flamewaker and the early 1 mana drops, along with Mirror Image to stop aggression does wonders. Here is where Arcane Anomaly really shines. I love those Mana Wyrm + Arcane Anomaly + Mirror Image + Coin plays on Turn 2. Really takes Agro Shaman by surprise.

I've tech'd in an Eater of Secrets for the secret hunter and Ice Block variant mages. Seems to be a nice pocket tech, and not a bad early body.  Also, keep it ready for when your spell opponent drops his Yogg - which reliably puts 2-6 secrets into play for a massive late game Eating. Also, one arcane explosion for the Paladin Bubble decks and Moroes token Druid/Paladin, and which synergizes nicely with Cult Sorcerer for a 2/3 damage AoE.

I'm looking forward to trying out Babbling Book when it is released, but don't think it will synergize with this deck. Babbling Book really needs to be in a Bran deck, where you can draw 4 spells on Turn 5 with Bran + Book x2, along with other potential battlecry synergy cards. 

*Mulligan for 1 mana drops and 1 mana spells. Arcane Anomaly + Mana Wyrm + Mirror Image is your dream hand. Arcane Blast is good mulligan vs. Tempo Mage mirror to deal with their Cult Sorcerer/Apprentice. Also good against Beast Druid for their new 1 mana 2/2. As well as Zoo. Favor Arcane Anomaly over Mana Wyrm as a 1 mana mulligan vs. zoo. It can do nicely against a Flame Imp or Dark Peddler, and is excellent with Cultist for a 4 mana removal.

Also, don't be afraid to use Fireballs to clear troublesome 5+ health minions. You will draw at least one more Fireball type face damage spell with your Tombs/Conjurers, and can use your Firelands Portal to face to close out the game.
