In anything but 1v1/2v2, Shadow Tag potentially can outright kill nearly what ever you want, if given to the right Pokemon.
Of course, the exceptions being Shed Shell users, Ghost types post Gen 6, U-Turn (as Volt Switch will fail against Ground types), and Prankster Baton Pass/Parting Shot (as they will fail against a fast taunter, but priority bypasses it).
It can kill walls that otherwise are the only counters to a sweeper, or kill wallbreakers that otherwise are the opponent’s only way of breaking past your cores.
