Whismur Movesets & Competitive Sets

At its absolute minimum, Whismur reaches a glacial 6 Speed, which lets it move ahead of almost everything when Trick Room is up. Hyper Voice is a powerful STAB move that has great neutral coverage, making it the perfect choice to use as Whismur's main attacking option. Fire Blast hits Steel-types that resist Hyper Voice, such as Ferroseed and Magnemite, super effectively. Shadow Ball is used in the third slot to hit common Ghost-types such as Gastly and Frillish. Lastly, Ice Beam is mainly filler, but is Whismur's strongest move against the otherwise dangerous Lileep. Bulky Fighting-types, such as Mienfoo and Timburr, cause this set problems with their super effective STAB moves. A bulky Pokemon that resists Fighting-type moves would be a good choice; two good options for this job are Shelmet and Grimer. Munchlax and Lickitung have high HP and Special Defense, so they can tank all of Whismur's moves effectively. Fighting-types are therefore good teammates for Whismur, as they can take a hit and heal off the damage with Drain Punch. Whismur also needs teammates to set up Trick Room, and Duskull, Porygon, and Slowpoke are all good choices.

This is the best and probably only set that Whismur can run efficiently. Return is its strongest STAB attack, capable of dealing large amounts of damage to anything that doesn't resist or isn't immune to it. Thunder Punch and Ice Beam give Whismur "BoltBeam" coverage, resisted only by Magnemite and Chinchou in Little Cup. This combo is also effective because Thunder Punch hits Water-types on their typically lower Defense stat while Ice Beam hits Ground-types on their weaker Special Defense stat; this allows Whismur to become a powerful Trick Room wallbreaker. The final slot is purely a matter of preference: Shadow Ball smacks Duskull and other Ghost-types for super effective damage, while Fire Blast allows Whismur to beat Bronzor and Magnemite -- two Pokemon that can otherwise wall this set. Life Orb is necessary so Whismur can deal as much damage as possible while still having the ability to change attacks at will. Whismur's nature can vary - a Brave nature will boost its physical moves further, while a Quiet nature will enhance Whismur's special moves. The EVs maximize Attack and Special Attack, and the remainder adds two points to Defense, one to Special Defense, and the other to HP. Since Whismur can't get down to 19 HP, the extra HP might come in handy. The most obvious support for this Whismur will be from Trick Room. The best Trick Room supporters are Ghost-types -- Drifloon, Duskull, and even Gastly are good for this. Ghost-types are important because they have good defensive synergy with Whismur. Stealth Rock support is also nice, so less Pokemon will be inclined to switch around on Whismur, especially if they mispredict. Pineco resists Fighting-type attacks, can set up both Stealth Rock and Spikes, and use Explosion to possibly remove a wall before it goes down. If Whismur isn't using Fire Blast, Bronzor walks all over this set. Magnemite will help a lot in that case, but it shares a common weakness to Fighting with Whismur. Since Munchlax also gives this set some trouble, Fighting-type partners are very useful. A bulky Machop is great, since it can also take advantage of Trick Room with its low Speed.
