It is very bulky, it has 4 (FOUR!) recovery moves, and on top of that it also has good Atk, an Atk boosting ability, and access to Bulk Up... That's one hell of a movepool right there! I even started a Research Center topic on it
I use the Bulk set with Leaf Blade, Milk Drink, Bulk Up and Rock Slide. Garchomp and Zard take care of any steels that try to stop it. Srsly, that thing is a threat with the right support.
