Most of his sets won't work that well in OU, there are better pokes at the roles, he just used an all bug team. Also Thunderbolt on gengar isn't that good but on the other hand sheer force landous is a great mon.
The standard set can be found here http://www.smogon.com/bw/pokemon/landorus
Also you could even use scarf lando > Scarf Kym-b, I find Kym-b works best as a heavy hitter early/middle game.
