Keep in mind Riding A won't allow for Phantasmal Species. 

Golden Rule to B. 

Independent Action to C since there's no backup from the Class Container; if he was Archer then B would be fine. 

Why doesn't he have Voyager? Seems like something that's more or less mandatory.

The NP itself is fine on face, but I'll have to do my own research since I'm not familiar enough with Sinbad's legend to say decisively. Don't try and do dumb stuff like jumping onto a Servant's shoulders and trying to activate this. 

Since this "destructive crash" is a Broken Phantasm, expect prana costs to be significant.
