Shake all with ice, pour into chilled rocks glass over fresh ice. It is delicious.
Notes: I don't have that luxardo, used half Campari half bitter rhubarb liqueur; doubled the pineapple juice because I literally just made it and it's amazing. This doesn't need 1/3 oz of agave, less is better. Finally - it was quite difficult to make one of these with those teeny measurements. I would recommend making two at a time.
