As Unexpected Results is costing 3-mana now, it is time for this deck to shine!

Mana Addict and Vex Crow are stars in this deck. They create incredible tempo with Twinspells. Also Vex Crow and Sea Giant synergy is so sweet and surprisingly quite overlooked for a long time. Conjurer's Calling allows you to get most out of your Sea Giants.

3 card combos are rarely work in Hearthstone. Yet, Elemental Evocation + Celestial Emissary + Unexpected Results combo on turn 3 or Elemental Evocation + Cosmic Anomaly + Unexpected Results combo on turn 5 appear to be exceptions for this particular deck. Those cards have synergies with other cards like Frostbolt, Mana Cyclone, etc too. So they're not useless out of those combos.

Things need to be kept in mind while playing:

• Casting Conjurer's Calling on Vex Crow will give you one 2-drop, two 4-drops.
• On turn 5; Khadgar + Unexpected Results combo will give you five 2-drop minions with approximently 7-10 total attack. You can always play Conjurer's Calling on two of them the next turn. 
• While Khadgar is already on board; playing Elemental Evocation + Celestial Emissary + Unexpected Results combo will give you; two 2-drops and four 4-drops on board.

Mulligan:

• Always hard mulligan for Mana Addict, Sorcerer's Apprentice, Mana Cyclone and cheap spells like Ray of Frost or Mirror Image. 
• Do not hesitate to play Sorcerer's Apprentice for tempo and Ray of Frost for defence against Aggro decks.
• Mech Hunter and Mech Pally tend to build up humongous minions by magnetizing their Mechs. Mirror Image, especially with Khadgar, slows them down nicely.  
• If you have the coin, you can keep Unexpected Results for turn 2 play. You may end up with having one Sorcerer's Apprentice and one Faerie Dragon on board.
• Vex Crows are the stage 2 of the deck. Make your opponents waste their single target removals on Mana Addicts, Sorcerer's Apprentices and Stargazer Luna first.
• Sea Giants perform better if you draw them from the deck.

Enjoy :)

The deck is tempo/aggro deck. And like every other tempo deck, if you go too much defensive you'll lose the board at some point because the deck is not made to be defensive. It is designed to overwhelm your opponent with minions.

5 minutes ago, i played vs Deathrattle Hunter for example. My starting hand was Sorcerer's Apprentice, Vex Crow and Stargazer Luna . I discarded Vex Crow and Stargazer Luna and i got Ray of Frost and Magic Trick. At the start of my turn i was lucky enough (it actually has a nice drop rate in this deck) to get Mana Addict. At turn 1 he played a 1/1 deathratle minion. At turn 2 i played my Mana Addict knowing that it would be very unlikely to have an answer at turn 2. I was right, he didnt. He played another 2 cost mech minion. At turn 3 i got a Sea Giant. I landed my Sorcerer's Apprentice and used both charges of Ray of Frost on both of his minions as well as Magic Trick which gave me a Mirror Image. I also played Mirror Image and went face with my Mana Addict doing 9 damage at turn 3!!. I really felt kinda bad for the guy. He played Unleash the Hounds in order to destroy my Mirror Image  filling his side of the board with minions. Next turn i got Conjurer's Calling. Played Sea Giant  into Conjurer's Calling and that was it... next turn i used my other Conjurer's Calling and he conceded.

Another good thing about this deck is that is not as popular as other mage decks, making your opponents mulligan their starting hand assuming you have a Dragon Mage or a Cyclone Mage deck.
