Tornadus-T is one of the best offensive pivots and Defog users in the OU tier and a solid pick on a variety of team archetypes ranging from offense to balance thanks to its great Speed tier, decent bulk, and more importantly its access to Defog, which allows it to beat entry hazard setters such as Clefable and Ferrothorn with the right set. In addition to this, Tornadus-T can take care of some problematic Pokemon like Kartana and Mega Medicham with Hurricane, a strong Flying-type STAB move with great neutral coverage, which makes it a pain to switch into for some teams. Although Tornadus-T is vulnerable to Stealth Rock and all forms of status, Regenerator gives it the longevity to continually check these threats throughout the course of the game and get rid of entry hazards.
