When I first used it I thought it was gimmicky at first, but it has shown to be quite a potent combination. Together, they form a solid core that is sure to aggravate any team that relies upon physical offense to do damage. This core centers upon getting CB Landorus-T to get a powerful EQ's against the opposing team. Landorus-T hits a poop-producing 640 attack with CB and is so powerful it can always 2HKO Ferrothorn with EQ. U-turn has some awesome utility for allowing me to get a double Intimidate off while tanking a hit for a team mate. Landorus-T's problems with Gliscor and Skarmory is where Gyarados comes into play. Taunt prevents Skarmory from healing and Waterfall can take out Gliscor when the opportunity arises. U-turning Landorus-T out into Gyarados in front of Skarmory is one of the most common setup oppurtunities for Gyarados is possibly one of the most satisfying things to do. Lastly, Hitmontop has good synergy with Gyarados by being able to take out Ferrothorn's hazards and Ferrothorn itself. Of course, spinning away SR allows Landorus-T and Gyarados t switch in much more frequently to get hits off and to sweep. Landorus-T used to have a bulky spread with 252 HP but the speed seems to be more useful although I wish I could go back sometimes.
The best partner for this core is a bulky Grass type to consistently switch in and take out bulky waters who use Scald. More importantly, to take on Rotom-W who could be problematic. Shaymin, Celebi, and Roserade are the best in that regard and complete an offensive core with Gyarados and Landorus-T. Ferrothorn can also work, but not being able to heal burns from Scald is annoying.
Edit: Forgot to mention a really strong special tank makes a great partner as well. Snorlax, Blissey, Latias, and Chansey are what come to mind since they can tank a variety of special hits. Basically having the special side locked down while having all these intimidate users makes the team in question very difficult to break.
