While Supreme Archeology may not be the most successful quest on the block currently, and Plot Twist Warlock is certainly not Tier 1, I have found that this deck does in fact have one huge advantage:
It runs rings around Control Warrior!
(And it does pretty good against most other decks as well, too)
Ok, it might struggle against super-heavy aggro decks; unless you can get a few Hellfires to clear and then stabilise with heals and taunts. That's to be expected.
But against most control decks, you will find yourself in a really strong matchup.
The obvious combos to be aware of, are getting Dollmaster Dorian or Fel Lord Betrug out and playing Plot Twist to create a board.
And if the board is cleared, not only are you likely to get a number of deathrattle-spawned minions (like 7/7 mechanical dragons), but also the Anubisath Warbringers do an amazing job of buffing your hand to crazy sized minions.
Getting low on life? Attach your 9/8 Zilliax to the 7/7 Mech Dragon to heal for a cool 16 damage. And start dropping massive taunt minions to dominate the board.
But this isn't where the fun stops. Plot Twist aids in getting rid of some of your opponent's removal spells. In the late game, your quest will automatically complete and you can start getting 0-cost minions into your hand.
It may not rock Tier 1, but this is by far one of the most fun decks I've played in a long time and doing it at the expense of Control Warriors who force the game to last for 40 minutes only to die at the end... well that's just awesome... :-D
