A deck exploiting the broken capabilities of Brain in a jar and Goryo's Vengeance to sling out HOT. FRESHLY BAKED. EMRAKULS free of charge. Before explaining the deck, two things should be known. One, due to Wizard's ruling on when split card's fuse cost is paid, Brain in a Jar allows you to freely cast both sides of Breaking and entering when it has two or six charge counters. Secondly, despite Emrakul's last ability that shuffles her back into your library when she's sent to the yard, because entering is cast simultaneously with Breaking, Emrakul can be selected as the creature in your graveyard to bring out.
So, there are two primary ways this deck gets Emmy out. The first is brain in a jar. A perfect sequence would look like this.
T1: Land, play voltaic key.T2: Land, play brain in a jar.T3: Land, Tap Brain, add a counter then cast any one drop instant/sorcery, preferably serum visions so you can scry Emmy to the top of your deck. Tap your second mana for voltaic key and untap Brain. Tap your last mana to play breaking/entering on yourself. While you're discarding the eight cards from breaking, if one of them is Emrakul place her onto the battlefield and win the match.
The second method of getting Emmy out is with Goryo's Vengeance, which can actually be done faster, but you will lose her at the end of the turn leaving your opponent with 5 life and you with zero threats, which is why I'm reaching out for advice on this deck. Anyway, this method would look like this.
T1: Land, play Hedron crab.T2: Land, Triggers crab's ability, hope Emmy comes up. Respond by casting Goryo's Vengeance. Put out Emrakul and swing for 15 with Annihilator 6.
Cards like Thought scour and Glimpse the unthinkable are the other methods to get her into the yard. Lastly Coretapper is used to create charge counters on Brain to possibly cast breaking/entering for it's 6 cmc if it's late game and you haven't got out Emrakul. Because this won't always happen perfectly every time, I placed the 4 counter-squalls in to stall the game. Not entirely sure if they're needed yet due to this being an ALL-IN combo deck.
