None of them use held items. I understand that this is ORAS, but if I were to give a list for all "3" different Hoenn games then I would reach the answer text limit. RS and ORAS are fairly similar, while Emerald is pretty different. Here are some links if you can't see Bulbapedia. Emerald Ruby and Sapphire I cannot find any website that gives information on what movesets the gym leader rematches in Emerald have, so this is going to have to do. I don't think there is better information on Google on a safe website
