What up ATTIBOT.
Others have already mentioned your TTar weak, but I'm more worried about Magnezone + DDMence as Scizor is like your only mon thats gonna be able to revenge kill DDMence other than ROCKBOT (hmm Azelf revenge killing Salamence, this sounds like our frontier match >___>). It isn't even like DDMence doesn't have anywhere to setup because it can setup on CB Earthquake and Rotom's Overheat. There is nothing i can do to immediately fix this problem, but I suggest trying out Dragon Pulse Heatran a little more.
Dragon Pulse also helps against Draco Meteor / Surf / Hidden Power [Fire] Latias as the only defense you really have against Latias is Scizor and ROCKBOT, and Scizor is OHKO'd by HP Fire and ROCKBOT may not be alive because it's a suicide lead. Dragon Pulse tears off a nice chunk of LOtias on the switch so you don't have to predict as much.
5 stars, congrats on the frontier. Very STRONG team boy.
