Basicly get the turn two Tangrowth with Sceptile GE's Body making it hit 60 and 20 to two benched pokemon. Then get both your techs out which are Nidoqueen and Shaymin Lv.X. Making hit heal 20 Inbetween turns and destroying Kingdra with the Resistence. I originally thought of Wailord but Tangrowth just looked to be alot better. Some people don't play Call energy due to Sceptiles body and having to quip three energys but I think Call energy and getting the turn two Claydol can make big game changes.

Thanks
