you know, i have a move set that has been working for me quite well.
item= leftovers
-iron defense
-iron head
-protect
-leech seed
ev's= 252 hp/ 100 def/ 156 spA
i start this set by bringing out a drizzler, then send out ferro. doing this minimises fire damage, increasing its overall defences. iron defense is to counter any physical arrackers, and punish them severley for it. ive encounted many conkeldurr, and destroyed alot of themby just using iron defense 2-3 times, tnen seeding them.
ive also encountered alot of slow pokemon, such as shuckle, and used iron head to take care of them.
