this deck is all about the quick completion of Final Showdown. 

Our payoff is thinning our deck and playing a lot of giant minions all at once. To this, we have Arcane Giant, which will obviously be very cheap, if not free, by the time we've completed the quest and/or played Demonslayer Kurtrus. Our other giant is Ur'zul Giant which can be duplicated by Felosophy. this giant does not cheaper on its own, but its effect is persistent even if it's in your deck. So, just play Expendable Performers [/card] once, and they will be free for the rest of the game. [card]Irebound brute will be very easy to play for cheap, I mean, it has the same condition as our quest; we better be pretty freaking good at drawing a lot of cards in one turn.

An alternate win condition lies within stormpike quatermaster. Even late into the game, our hand can go from 2-3 cards to a full hand. with cheap cards discounted by demonslayer kurtrus, stormpike quartermaster can get some nice buffs in. And there are some premium targets for handbuffs in this deck, such as Lady S'theno and Coilskar Commander. You don't even need that many buffs for those cards to be insane. To ensure that the buffs land on what we want, I run two copies of Dispose of Evidence. There will often be times when your big cards are interrupting your outcast abilities, and dispose of evidence is so good at fixing that issue.

also Yogg-Saron, Master of Fate.

Try the deck out, the turns are very player-involved. It's for people who like to play for lategame, but hate sitting around playing one card per turn. As a result, this is not the easiest deck to pilot as there will often be many lines of action while playing. My advice is to plan your turns, at least one turn in advance, especially when completing the quest. 

Enjoy. Let me know if this deck is fun or is too greedy and just falls flat on its face. I've been winning games that are not against aggro. This deck just doesn't really do much early game besides cycle cards, all the while you are getting slapped in the face with a swordfish or totem.
