Magnezone

Magnezone's near-exclusive access to Magnet Pull gives it a very unique and valuable niche in the OU metagame as a trapper and eliminator of Steel-types such as Ferrothorn, Mega Scizor, Skarmory, and Celesteela. It also functions as a solid revenge killer with Choice Scarf, being able to check a number of dangerous Pokemon like Kartana, Mega Scizor, and weakened Celesteela. However, its lackluster Speed stat, even with a Choice Scarf, means that it typically struggles to retain its utility after it has trapped what it aims to trap; it is often forced to take a hit before it can attack with its other sets and doesn't have recovery to offset this damage. Its good set of resistances is somewhat undermined by its weakness to three common types in Ground, Fighting, and Fire, which makes it easy for dangerous Pokemon like Mega Lopunny, Landorus-T, and Mega Charizard X to KO and leaves it unable to safely trap Heatran and Excadrill.
