Very situational but can be deadly. Haven't fully figured the best Speed and HP I need though.
In Sand, it can survive most (or any) special hit that is not Focus Blast. As I said, its very situational but what I usually do, is switch in into a resisted/neutral special attack, Dragon Dance and hope my weakness Policy gets activated and proceed to sweep with a +1 speed and +3 attack.
I think Rock Polish would work in place of DD.
A more experienced player could find a better EV distribution to make this thing work. But, it will always remain weak to priorities and it could only work against special attackers, as I found out T-tar doesn't take SE physical hits to well.
