CORNBRINGER
So i noticed he only really uses his zanpakuto to do a flying slash that severs space. if his sword is an elemental type like toshiro or the yamamoto he should have some more space manipulation even if minor. like instead of sending (whatever that fang techniques name is) flying he could keep it on his sword like how ichigo coats his sword in Getsuga Tensho. then he can use Hiken - Tsubame Gaeshi, Secret Sword: Swallow Return. He could also mix his space manipulation with flash step to get something like the white tower commander from the book eating magician. It will be lame if his shikai only gives him one move.
