@electrolyte Thanks for the great rate. I have tried pursuit over low kick and it has helped a lot to remove resists to terrakion's close combat, i have definitely kept this. I tried the deoxys set and i found that i couldnt set up hazards as well as i could before being ko'ed so i have kept the set the same and gone with Novaray's advice. I have changed head smash for stone edge and it was really a mistake on my part that i didn't have stone edge before. I was just a bit reluctant to put hp fire on deoxys because my rotom counters it hard with WoW and hydro pump.
@Novaray Again thanks for the great rate. I have changed psycho boost to taunt and it has really helped me with stopping set up sweepers like SD Lucario. I have changed donphan's ev spread to the spread you mention but I have not changed the nature as i still want to be doing damage while spinning away hazards. Also, i have changed Salamence's nature to naive and it has really helped to ko ferrothorn which i could not do before.
All changes made will be put into the OP.
