BTW, still got that team, and I'm thinking about some changes, since I'm using it competitively.
Currently it's Azelf/Mamoswine/Heatran/Terrakion/Rotom-W/Zapdos. I need something that can help me take Water attacks; I'll probably put it over Mamoswine, or if it has Stealth Rocks, Azelf. It should be able to help me revenge things well. Got any ideas that fit?
