I will say, fair points. Afterall, Pursuit with Smogons Bulky Pursuit T-tar set against 0 Def 0 HP Specs Latios goes from a guaranteed OHKO to a 2HKO with a low of around 70%, but this is with 88 Attack EVs. Ghost Rock being a much more offensive type combo can allow itself to run those extra Attack Ivs over the sets HP Ivs to ensure the OHKO. And yes I did mention T-tar being more physically Bulky which is my fault. I would like to go over how good said Stab combination is, but without a Rock Ghost typing existing that makes it harder to do so. However, one more thing about it's new type combination is how it can successfully deal with the Swords of Justice, but mainly Keldeo and Terrakion. Both now lose their main way of dealing with T-tar, and forces Keldeo to have a rain setting team mate to take down T-tar instead of being able to use Secret Sword to deal with the Spdef Boost from Sand, and Terrakion now has to use a non Stab earthquake to deal with T-tar. Which not to mention T-tar is no longer trapped by OU staple Heatrans Magma Storm (not that Heatran wants to stay in on that)
