The Carni is one of the techniques that Eddie Bravo developed as part of the 10th Planet system. The tech comes into play when you are at New York and a person steps over the leg that was at their hip.
This technique will take a certain level of flexibility to do. Work on opening up your hips and you should be able to nail it.
This is a very unorthodox submission. Because it comes from such a weird angle most people will not be ready for it.
With practice you should be able to get the tap. If not, you can always force them to roll so that you get the sweep & pass.
This technique can be used in combination with the No-Collar choke. From New York you can go either way.
