Heat the oven: Set to 375°F (190°C).
Lightly grease a 9x13-inch baking dish.
Make the sauce: In a bowl, whisk together the green enchilada sauce, salsa verde, and sour cream. Stir in lime juice and a pinch of salt. Set aside.
Sauté aromatics: Warm olive oil in a skillet over medium heat.
Add onion and cook until translucent, about 3–4 minutes. Stir in garlic for 30 seconds until fragrant.
Build the filling: Add shredded chicken, corn, diced green chiles, cumin, smoked paprika, salt, and pepper to the skillet. Stir to combine and warm through, 2–3 minutes.
Off the heat, mix in 1 cup of the shredded cheese.
Warm the tortillas: Wrap tortillas in a damp paper towel and microwave for 30–60 seconds, or briefly pan-warm them, so they’re pliable.
Assemble: Spread 1/2 cup of the sauce over the bottom of the baking dish. Fill each tortilla with about 1/4 cup of the chicken mixture, roll it up, and place seam-side down in the dish.
Top and bake: Pour the remaining sauce evenly over the enchiladas. Sprinkle with the remaining 1 cup of cheese.
Bake for 18–22 minutes, until bubbling and lightly golden at the edges.
Finish and serve: Let rest 5 minutes. Garnish with cilantro and jalapeños if using. Serve with lime wedges.
