You all got the sets down I believe so I will discuss his abilities, Throlololololo!!!
Inner Focus: how cute, protects you from flinching, don't use it!
Guts: U Mad Throh? Well I see no since you get your buff on attack to hit some NU mons harder, use this!
Mold Breaker: meh guess you could hit Haunter and friends with Earthquake but there is Payback!!!
