A very close copy of this deck: http://pennydreadfulmagic.com/decks/303/The only real changes to the list are the addition of two Fact or Fictions in the sideboard and two addition Wipe Aways in the main.

The deck takes advantage of a powerful interaction between Worldgorger Dragon and Animate Dead. When Animate Dead enters the battlefield it targets the Worldgorger Dragon in the graveyard, brings it onto the battlefield, and the Dragon's ability triggers to exile all of your permanents. While this ability is on the stack you can add mana from any untapped lands and then let the Dragon's ability resolve. Animate Dead leaves the battlefield and triggers to put the Dragon back into the battlefield, which triggers the Dragon's ability to return all your permanents from exile. You get your lands and the Animate Dead back, which triggers to target Worldgorger Dragon in your graveyard. Lather, rinse, repeat.This infinite cycle may be taken advantage of in three ways in this deck. Mainly through Nephalia Drownyard, but one copy of Bloodrite Invoker and Grindclock give two additional one-of ways to combo off. It is a pain in the butt on Magic Online, but if you get into the rhythm it can go quickly. Many opponents are kind enough to scoop when you have demonstrated a loop that ends in their death. Two Coffin Purges in the main deck can ensure that if an opponent makes you go through the loop with the Drownyard or Grindclock you can end the cycle by exiling the Dragon from the graveyard in response to the Animate Dead trigger and then pass the turn.

There are several matchups that the deck fairs very well against, including non-interactive combo decks, ramp strategies, and less controlling Cloudpost builds. Aggro decks are a fair fight, especially RW, where instant speed removal is either damage based, and therefore unlikely to kill the Dragon, or based on creatures attacking. Instant speed removal is an enormous weakness of the deck pre-board, so there are Negates in the main to help protect the combo. The sideboard has more counters to bring in as well as the two additional Wipe Away for the graveyard hate, which is so real. Purge the Grave is a major annoyance, as well as Ground Seal, though this is precisely the reason we have Repeal. Scrabbling Claws is a big annoyance, but Wipe Away is incredibly effective, and running two in the main has come in handy a couple times so far, especially with Elixir of Immortality which Cloudpost builds favor.

The turn 3 kill is an opening hand with Worldgorger Dragon, Nephalia Drownyard, an Island, a Swamp, Frantic Search, and Animate Dead. On turn three you can combo off and most of the time the opponent will scoop. It is unusual but not incredibly rare. I do not find that I have to mulligan aggressively with this deck, as it churns through the cards in it very efficiently, and often I can chain together multiple draw spells and my opponent's end of turn, bounce a lock piece, and then untap and combo off. This deck, like most combo decks, favors patience and knowing the right moment to strike.

My match record with the deck is 5-3 so far, and several of the games were given away by my navigating the learning curve of the deck and making some fatal misplays or generally not understanding the correct moment to use Frantic Searches and chaining together draw spells.
