Preheat the oven to 325 degrees.
Mix together the salt, pepper, chili powder, paprika, onion powder, and garlic powder.
Dry the brisket well, and rub it all over with the spices.
On medium high heat, heat the oil in the Dutch oven and sear the brisket on all side.
To the pot add the wine, mustard, onions, garlic, bacon, bay leaves, tomato sauce, and brown sugar.
Cover and bake the pot for three hours.
While the brisket cooks, make the corn salsa by mixing together the corn, cilantro, jalapeno, red onion, lime juice, and pepper.
Remove the brisket from the pot and slice it thinly.
Heat the tortillas in a buttered grill pan.
Fill the tortillas with sliced brisket, some of the sauce, and the corn salsa.
