Well is there any reason to use it over Thundurus-I? :P Missing out on outspeeding Latias is huge! and Terrakion/Garchomp too if those count. Now you can't U-turn out from Latias before it OHKOes you with Draco Meteor :(
Scarf sucks, why will you use it over Zekrom? Maybe U-turn but its piss weak.
Thundurus-T's analysis is floating at the moment. I am not willing to approve it at the moment lol because it sucks to be frank. It doesn't even get many set up opportunities. Zekrom is better in most cases. Also its SR weak.
