Rim a margarita glass with a lime wedge and dip it in chili-lime seasoning or Tajín. Set aside.
In a cocktail shaker, add tequila, orange liqueur, lime juice, mango puree, habanero slices, agave syrup, and a handful of ice.
Shake well until chilled, about 20 seconds.
Strain into the prepared glass filled with fresh ice.
Garnish with a lime wedge and mango slice.
Serve immediately and enjoy the spicy-sweet flavor!
