Ferrothorn

Ferrothorn has always enjoyed a spot in the top 5 in standard OU thanks to its incredible bulk, access to an array of support moves, and unique defensive typing giving it resistances to the top threats in the tier. One would think, then, that a metagame infested by Shadow Tag Chandelure makes it incredibly difficult to do its job. However, this is not the case. Sure, Chandelure obliterates Ferrothorn with any Fire-type attack bar a rain-soaked Flamethrower, but with the proper precautions, such as the vital item Shed Shell, Ferrothorn can work around Chandelure to perform its regular duties, from laying down hazards to dealing nasty status to your opponents. Ferrothorn is just one of those Pokemon that can fit into just about any team style, since the support it supplies is universally important.
