You should mention SubBU in at least OO or the AC of the physical set imo. Prankster Sub lets you scout for priority and take advantage of the switches a supposed Hurricane forces.
The BU and U-turn explanations should be in SC not AC and OVERVIEW -> Overview, OTHER OPTIONS -> Other Options, and CHECKS AND COUNTERS -> Checks and Counters.
Some good teammates should definitely be mentioned in the AC of each set. I mean, there's none in the entire analysis. For the first set, mention that Politoed support is mandatory. SDef Jirachi's the best counter, mention ways around it like Dugtrio and Landorus. Do the same for SDef Rotom-W and Bronzong. Mention that some good entry hazards (Spikes + SR) make it possible for Tornadus to get around Jirachi. Probably throw in something for Jirachi because it resists BoltBeam. A Starmie counter like Rotom-W is nice because Starmie is one of the few Pokemon that can outspeed Tornadus. For the second set, mention that the lack of reliance on rain is such a big selling point. Mention entry hazards again because physical Tornadus isn't /that/ powerful. Throw in Magnezone because Skarmory / Jirachi can be a big pain in the ass. You get the idea.
Oh, and the Pokemon is Tornadus, not Tornadus-I.
