You sure know when a pokemon is incredible usufull, those 3 (Scizor, Ferrothorn, Gastrodon) can make a whole strategy to fall apart if you don't have a solid
counter to then.
Gastrodon rise to fame came with the incresing on Rain Team, but soon enough people started to use it outside of the rain. Thanks to his bulk he found niches on every themed team (Sand, Sun, Rain, Hail, TrickRoom and Goodstuff), mostly as a check to the always famous Rain Teams.
Gastrodon even have an impact on pokemons moves choices, in the case of Suicune, the premier bulky water, he need to choose what will wall it: Ferrothorn or Gastrodon (HP Fire or HP Grass), Rotom-W, omnipresent in all Goodstuff teams, have the same tough decision, there are even Chandelures that prefer to run Energy Ball in place of Trickroom or protect, and for Jellicent energy ball and Giga Drain are a bless.
But don't overhype the slug (btw I always prefer Pink gastro over those ugly East Sea gastrodon) if there is not water type attack to redirect Gastrodon will become a punching bag in most case, or you could have a trick room under the sleeves just in case. Everybody want to OKHO gastro but in the case this is not possible apply the Cresselia Law to him (eliminate all partners first), since gastrodon may not be able to resist being targeted by both offenders pokemons.
I've been using an unorthodox Gastrodos Set (in the item, that's it)
(yep, like the killers whales) (Gastrodon) @ Zoom Lens
Ev's (I may lie about it): 252 HP / 252 SAtk
IV's: 0 Spd
- Muddy Water
- Earth Power
- Recover/Protect (you choose)
Since Gastrodon is an already slow pokemon let's make him benefit from that!. With Zoom Lens attached (and you being slowest that your target) Muddy Water have perfect accuracy (102% to being mathematecally exact) and Blizzard have a good 84% accuracy. The only think you should keep in mind is the speed tier, if you are battle against TR teams Gastrodon may be fasters than opposing pokemons.
