...really?
I feel like all of those items are so questionable. Tornadus-T is too frail to do anything valuable with Eject Button, and benefits so much from Life Orb. Thundurus... magnet? Really? Not an Electric Gem, not a Life Orb, but magnet? And Landorus with Scope Lens? Again, so many better item options - Life Orb, Leftovers, a boosting Gem, or a choice item.
Your sets look fine, but the items... you'd really have to sell me on them, personally!
(Edit: Personally disagree with Taunt/Rain Dance on Tornadus-T. He doesn't get Prankster anymore, if I recall right, so even though his natural speed is quite high he's beaten/taunted by Whimsicott, Sableye, and Tornadus-I.)
