So why would I use this over Latios, Hydriegon, heck even Kyurem-B. Lati@s are faster, hit harder, potentially have a better typing and can get past special walls with Psyshock. Both Kyurem-B and Hydriegon are much slower but also hit a fuckton harder (Hydreigon in particular has the option of using a +SpA nature) and having alternate STAB moves in Dark Pulse and Ice Beam aiding in coverage.
Specs Mence was also rejected in thr last Salamence update, so you need to explain why it works now, at the expense of the above pokemon I just listed.
QC REJECTED 1/3
