Honestly, Mystogun is overrated. His only on-screen feat is that he managed to go toe to toe with Laxus during the Fighting Festival arc for a couple of minutes and then he left. He should be supersonic in speed and about cb lvl in attack potency and durability. Given the power lvls of everyone after the 1st skip he is rather weak. Silver was one hell of a force to be reckoned with. Town to City lvl attack potency and durability and hypersonic speed with insta freeze. Mystogun is horribly outmatched here. Mystogun at his peak is around the same level of nowdays Lucy and that could be wanking him. Silver 10/10.
