Preheat the smoker. Set your smoker to 275 degrees F. I love using oak wood. You can also use cherry so you get that rich mahogany color.
Trim the brisket. Use a sharp knife to trim off most of the fat cap from the top of the brisket and all of the silver skin from the underside of the brisket.
Season the brisket. Sprinkle the brisket flat on all sides with a layer of the Spicy Sweet Rub.
Smoke the brisket. Place the brisket flat on the smoker, close the lid, and cook for 4-5 hours, or until the internal temperature of the meat reaches 165 degrees F.
Wrap the brisket. Remove the flat to a large sheet of butcher paper and wrap tightly, tucking as you wrap to ensure there are no big air pockets or exposed pieces of brisket.
Continue smoking. Return your wrapped brisket flat to the smoker, close the lid, and continue smoking at 275 degrees F for about 1-2 hours, or until the meat is very tender. The thermometer probe should slide in and out like it's softened butter and will likely read around 202 degrees F.
Rest the brisket. Remove the smoked brisket flat from the smoker to a baking sheet and allow it to rest for at least 45 minutes or up to an hour.
Make the corn salsa. Combine all the ingredients for your creamy corn salsa in a large bowl, then stir with a rubber spatula until everything is incorporated.
Assemble the tacos. Slice the flat against the grain into ½-inch thick slices, then chop into ½-inch cubes. Add the brisket to your tortillas, then scoop on some corn salsa, sprinkle on your favorite toppings, drizzle with the Texas BBQ Sauce, and enjoy!
