Alexander i have already tried the combo of Specs Moltres and LO Tornadus-T and it is a good one. Many of Moltres's checks and counters such as Ttar, Heatran, Chansey and Blissey are beaten by Taunt Tornadus-T, so just U-turn out and profit. Also Moltres can roast any Jirachi / Metagross / Skarmory / Bronzong who are looking to wall Torn-T, and can again come in safely with U-turn. I think that those 2 together are unwallable in OU (could be wrong though).
I never thought of this combo, it sounds very interesting and looks very dangerous as long as you have spins support.
