sakuya is more like a watcher. think of her like ammys alarm system. she also gather energy to ammy. its kinda,the sakura trees gather faith and earth energy,sakuya acts like a bridge transfering this energy directly to ammy. i believe this only works on the mortals world. since when you're fighting Yami,you're in the god's world,and ammy receives the energy directly from the believers. but analizyng the point,maybe sakuya had to transfer the energy too.
