This deck is a Bo1 deck and has 3 win conditions that work together: Cavalcade of Calamity, The Discard Package and Ill-gotten Inheritance/enchantments.

First, is Cavalcade of Calamity.  This wins games the most often in my experience.  You put 2 or 3 1/x's on the board and try to ruin them with the pings from this enchantment.  If you get 2 Cavalcades out  and have enough 1/x's out on the field the damage stacks up super quickly.  Clamor shamans are super important to this strategy because they shut down pesky blockers, and the orzhov enforcers use deathtouch to stall out the game with peons they don't want to attack into or block.  If you happen to get Goblin Instigators paired with Cavalcade it starts racking up the damage.  Legion Warboss is a good finisher for this strategy if it sticks.  Once you hit a critical mass of 1 damage attackers and Cavalcades, not even settle the wreckage will save them.

The second win condition is the discard package.  The fell specters help make this a viable strategy.  If you get one of those out and then Carnage for 4 mana, the Carnage does 7 damage if the opponent has enough cards to discard 2.  The fell specters also proc Cavalcade of Calamity, so the win conditions work together.

Before we get to the third win condition, there is one key player that props up both of these first 2 strategies: Angrath, the Flame-Chained.  The turn you cast him you can often steal a 3 drop that has buffed up (like a gatebreaker ram), attack into them with it and then just sacrifice it.  This really accelerates the Cavalcade of Calamity strategy.  He can also make an opponent discard and take 2 damage, so with the discard package if you have a Fell Specter out his plus 1 becomes 4 damage and discard a card.

The third win condition is Ill-gotten Inheritance and the enchantments.  Ill-gotten Inheritance lengthens your life and cuts into the opponent's with 1 damage drains every turn.  When they get down to 4 life, if you have 6 mana, you can pop the Inheritance for 4 damage.  It also enables Theater of Horrors every turn.  As long as you damage the enemy (which Inheritance does every turn), Theater of Horrors is just an extra draw with no hand size limit for that second draw.  It's also a great mana sink to burn through 4 mana at a time and ping the enemy for 1 damage.  These 2 enchantments usually become a win condition after your opponent has just wholly defeated one of the first 2, it's more of a finisher than a win condition all on its own.

The nice thing about this deck, is that sometimes you will just transition into a different win condition after the first one didn't work out (usually cavalcade of calamity).  I sprinkled in a little bit of removal (Vraska's Contempt and Cast down) just to have answers to things that I just can't deal with any other way.

I'll finish off by saying that this deck is really fun to play and win with, simply because there's such a variety of win conditions.  Thanks for your time.
