Griselbrand combo deck
The turn 1 Kill: black mana into Dark Ritual and then either Entomb, Thoughtseize, or Cabal Therapy targeting Griselbrand and then either
Shallow Grave
or Goryo's Vengeance, to put Griselbrand into to play, then proceed to pay all available life into the draw effect, usually 14 life for 14 cards, and then repeat to do same with an Emrakul, the Aeons Torn and then swing 22 lethal turn 1.
The second plan of action is same as first but if you dont have the right cards to get reanimate Emrakul, the Aeons Torn, swing with Griselbrand and draw 7 more cards and then chain Lotus Petal and Dark Rituals and cast Children of Korlis and sacrifice to gain all that life back, and draw much more and repeat, when you come close to decking you can force yourself to discard Emrakul, the Aeons Torn so your graveyard shuffles into your library and repeat until you just hard cast him and then take the extra turn and swing the rest and win that way.
While turn 1 kills are possible, its more common for turn 2-3 kills with the cantrips and such.

Sideboard:
Abrupt Decay - Catch all for things we don't like such as Rest in Peace, Chalice of the Void, Counterbalance
Chain of Vapor - bounces the troublesome permanents the turn we go off
Massacre
- hate bears and thalia, guardian of threben
Surgical Extraction - other combo matchups or can be used to save our own pieces cause we can fail to find the others if they try to extract a Griselbrand we only loose one instead of all of them
