Hearthpwn

A small disclaimer before we delve into this, I didn't come up with the idea behind this deck.  Credit for the idea goes to this reddit page: https://www.reddit.com/r/hearthstone/comments/b7uy7v/vargoth_otk_in_wild_quest_mage_3_or_2_card_combos/.  I highly recommend checking that page out, as they also have a few other ideas posted.  This was mainly put together as a way to cut down on the number of combo pieces required for an exodia mage to function (the Archmage Antonidas loop needed 5 pieces plus either Time Warp or Emperor Thaurissan to kill, while this only requires 3 plus Time Warp).  Now without further ado, let's get into the guide.

A quick rundown of the gameplan:
Freeze enemy minions while drawing through your deck (Be sure to save a copy of Research Project if your opponent has Ice Block, we'll get into why later).
Generate random spells with Cabalist's Tome, Primordial Glyph, and Magic Trick
Beat the quest with generated spells (likely falling back on Ice Block for survival at this point)
Complete either of the combos below to end the game

To combo, you'll want to cast Archmage Vargoth into Time Warp on the first combo turn.  This grants two extra turns to set up lethal.  On your first extra turn, cast 1-2 copies of Molten Reflection on Archmage Vargoth.  This will give you either 4 or 6 copies of Vargoth after his end of turn trigger happens.  On your second extra turn, there are two built-in otk's.  The first is Greater Arcane Missiles.  This does 9 on its own, plus 9 for each copy of Archmage Vargoth you have in play (this caps out at 45 damage with one Molten Reflection or 63 damage with two, generally enough to burst down anything without tons of armor stacking).  Alternatively, if your opponent has Ice Block active, you can play Violet Illusionist into Research Project.  Each copy of Archmage Vargoth will cast a copy of Research Project, drawing 2 cards each, while Violet Illusionist will prevent any fatigue damage you would take.  This draws a total either 11 or 15 cards, depending on how many Molten Reflection was played prior, including the draw your opponent will take on their turn.  Keep in mind that 7 draws into fatigue will deal 28 damage, and 8 will be lethal to anyone without armor.  This combo takes one more card to set up (illusionist and research project, as opposed to just the missiles), but the fatigue damage on your opponent's next draw will get around the otherwise unbeatable ice block.

One last note that I should cover is that Babbling Book will do a good imitation of Magic Trick for the 4 days between the release of Archmage Vargoth and the rest of the expansion.

I think that's about it for this guide, so let me know if you have suggestions or comments!
