To me it pretty much looks like a reverse Ninja Vanish, which there are no tutorials for.
It’s not ninja vanish. It’s a trick that can only be done via 5a. Yoyofactory had a tutorial for a trick like it duing 5a May, but, well you know…
I think that you throw a trapeze laceration and throw the counter weight through the loop and catch the CW but don’t let go of the string from your throwhand, I would probably make a tut if I could do it
