Just a sick, sick idea on how to abuse [scryfall]Sorin, Grim Nemesis[/scryfall] and the new Emrakul.
So, this might be a bit much, but stick with me. If nothing else, this might be a casual idea (actually, probably).
So, if you +1 Sorin and reveal an Emrakul, it deals 13 damage to your opponent. How do you make this work? Here’s some ideas. How do you get it on top of your library? How about with [scryfall]Conduit of Ruin[/scryfall] or [scryfall]Mortuary Mire[/scryfall]?
How do you get the Emrakul into our graveyard? That’s going to be a bit of a problem. Discarding isn’t that good despite all the Madness (or because of it), but you can self-mill. The deck does need some removal, so maybe [scryfall]Sinister Concoction[/scryfall] is an option, but I doubt that.
Of course, with cards like these, you’ll also want to ramp.
The deck needs some artifacts and instants as well, just so you can actually play the Emrakul.
In order to play the [scryfall]Sorin, Grim Nemesis[/scryfall] more reliably, [scryfall]Oath of Nissa[/scryfall] is good. So, how about this:
4 Hangarback Walker
3 Conduit of Ruin
3 Ulvenwald Hydra
3 Emrakul, the Promised End
4 Nissa’s Pilgrimage
4 Explosive Vegetation
2 Gather the Pack
4 Vessel of Nascency
4 Oath of Nissa
4 Sorin, Grim Nemesis
2 Mortuary Mire
4 Evolving Wilds
3 Drownyard Temple
Note that this is very rough sketch…
