So I just got a 2 star gaara and my 3 star kakashi today. I use shizune as a healer to cause high float.

Is there any particular order I can put them in? Because at the moment instead of comboing my gaara just ends his combo with his Coffin. I mean, my earth character can cause high float then knockdown with primary lotus, but my gaara interrupts. Any help?

Atm I have gaara in the middle front, my main behind him and shizune behind him. Then kakashi on the bottom row at the back.
