What is this trick??

Its the move where he just pulls the yoyo out and starts going into other trick. It happens around :50.

that is a pull start you need hubstacks like:
the plastic gind machine

       or matador spikes like a beysick

pull starts with a matador are much harder though

Nah, if you want something for Matador, get a SPYY. H-Spins have never been able to really pull it off.

Alot of that also has to do with the fact that he’s Yuuki Spencer and that freestyle just oozes with Epic.

Yuuki cooks with winsauce after all
