As Malamar is only weak to two types, it would be good to give him some Leftovers. But as this item is already been hold by another Pokémon of mine - and I don't want to take items twice - I'm searching for another item.
I would like to get his ability Contrary to use. So if a stat of Malamar is being increased, it's decreased instead - and vice-versa.
So I started asking myself how I can get advantage of Contrary. Are there any items that decrease a stat every round for example? Or a compareable item like Weakness Policy that instead decreases stats on event? Or are there better options?
My question is: Which items are best to use with Contrary?
