Thanks for the rate!
I'll test out Forretress and Rotom-W and see how they work. If Foretress can set up Spikes, I may switch Deoxys-D for a more offensive Volt-turner that can set up Stealth Rock.
As for Salamence, Rock Slide is only there for Volcarona. While it would help against steels, Volcarona is a big threat to the team. I'll try it out and see how it fits.
