Altaria has suffered throughout BDSP. Lost DD, lost Defog, lost Fire Spin rip but in PU, it can pull off some nice offensive sets. Choice Specs is dangerous to switch into, seeing how Dragon/Fire goes unresisted and it can carry EQ to kill the best dragon switchin Probopass. Altaria's typing also lets it check a lot off stuff naturally like Monferno, Pinsir if it doesn't click Stone Edge and Victreebel.
