The long and short of being annoying on Gyms (after Golden Razz stuff) is Blissey and Chansey, followed by things that support Blissey and Chansey.
The top things that people can attack with are
>Fighting Types - Quickest way to muscle past the two normal types, but also the easiest to counter>(Shadow) Metagross - Most mindless tap-through option avaliable, taking no damage from optimized Blisseys and handling most common Fighting Checks (Fairy)>(Shadow) Mewtwo - Difficult to check and handles common counters to Fighting with Psychic and Ghost coverage, but honestly fell the wayside after Ray>Rayquaza - Impossible to check without losing to one of the above (Closest would be Metagross, who Shadow Mewtwo beats, or Dendenne, which Ray can just muscle past)TL;DR version is Mandibuzz is probably the best defender most people don't think about. As Bulky as a Snorlax without weighing down to Fighting weak budget of a team.
