First of all, thank you everyone for your help in improving the Team. Second, I have indeed listened to your suggestions and did some testing. You were right, Venasaur is Better than Victreebel even without acces to an Ice Coverage move.
I still havent tested Heatran since I just recently read Novaray's posts. But I'm not too sure about taking out Scizor for him since he, along with Darmanitan, forms the offensive core of the team.
I'll keep you updated in how the team is going and once again, thank you.
