The Team Didn't Really Have A Specific Purpose, Just Different Types Of Attackers With Durant As A Baton Passer And Steelix As A Lead Tank. I ignored countering entry hazards because they only pose so little of a threat.
Although Chandelure Completely Cuts (Well, Burns) My Team Into Bits (Or Ash, For That Matter).
