>Not all of Trick Room's problems can be fixed with Taunt, however. Priority attacks are a huge threat to Trick Room teams, as they retain their priority even under the field effect. Mach Punch, Shadow Sneak, or a well timed Sucker Punch can spell disaster for one of your sweepers.
So yeah, in Generation V priority moves remain a huge threat. Watch out! :o
Hope I helped. :)
