Ankylosaur tails weren't quite *that* flexible.  Also, bear in mind that 
ankylosaurs were rather broad, hippo-shaped animals with big, wide rib 
cages.  The tail would have hit the animal's own side before it hit the 
rival.  If the tail were flexible enough, it would have wrapped around the 
animal and bashed it in its own head or neck; if not, the inertia of the club 
would likely have broken the tail shaft against the animal's side.  Neither 
sounds like much fun to me.
