RU, RU, RU. Not one of my most played tiers but still i enjoy it immensely. I've been meaning to try out Tyrantrum for a while now so I decided to go for it and he's been awesome unto now. Truant Durant is like the most viable thing in the world as entrainment makes pokemon dependent upon their abilities like Ambipom and Sharpedo useless. But the main reason for running entrainment truant durant is DUGTRIO. Dugtrio arena traps the pokemon truanted(new word) by Durant and protects on the turns they CAN move and hone claws on the next. After a few turns dugtrio gets the 4x attack and most of the times earthquake kills everything else. Dugtrio is extremely fast so we don't need to worry about its speed and just in case he gets one shotted by priority, dugtrio has a focus sash and thus the extremely powerful-when-hp-is-low reversal. Tyrantrum as I said has been awesome upto now EASILY setting up two dragon dances and then crunching everythiing to death. Exploud and carracosta are self explanatory as they help the team by doing massive amounts of damage.

Ambipom is a pokemon I use even in OU thanks to Technician+ STAB + life orb+ 100% flinch chance fake out and the awesomely powerful STAB last resort. Knock off is to hit ghost types and technician power-up-punch is to increase Ambipom's already high attack.
