I doubt it was intentional, but try to limit your reservations to one specific set. Reserving Trick variants covers a broad range of sets and prevents other players from submitting their ideas, it also goes against the rules of submission-- being limited to 1 set per week. Thanks!

The premise of this set is fairly simple; bait in walls that would normally prevent progress and claim surprise K.O's. Being difficult to scout, it bluffs many sets at once and is capable of baiting switches such as Heatran, Blissey, and Toxapex in order to cripple and/or kill them. Thunder is the move of choice, however, Focus Punch hits Heatran, Blissey, and Tyranitar for significant damage.
Its EVs are interchangeable for desired benchmarks, although max Def and max SpD are quite splashable. Bold / Calm are the preferred natures to avoid a tradeoff of speed for power when using Focus Punch, as rolls are still relatively favorable without Relaxed / Sassy.

Ice Beam is a niche option over Flamethrower, giving up coverage on Steel-types such as Ferrothorn, Scizor, and Melmetal in order to hit unsuspecting Landorus, Garchomp, and Dragonite more effectively.
This set is useful on teams that need a broad range of coverage to remove shared checks. It mutually benefits from offensive breakers and sweepers that punch holes in shared defensive checks in order to break down teams quickly.
