Alright, moving on from that shallow (lol) pokemon, Zangoose.
It strikes me as odd that Zangoose dropped so far this generation, being forced into Borederline last gen, being VERY useful in OU. So, why did Zangoose fall so far? To be honest, I'm at a lost.
1. Immunity grants it poison immunity, allowing it to avoid toxic spikes.
2. It gains elemental punches, as did all physical types.
3. Silk Scarf gained a 20 percent boost.
4. Close Combat.
My guess is that in a world full of offense, Zangoose could no longer go, Oh, Hey there wall, I'm going to set up on you, kay? It rarely gets that opportunity in today's game, and even more, with Close Combat running around everywhere, along with stealth rocks, spikes, among other types, it just doesn't have the bulk nor the speed to do what it needs to. Another problem comes from there simply being better options than a Zangoose with a silk scarf and quick attack, that being anything with Life Orb Bullet Punch. Steel types have also increased, as well as the ever present Rotom, making its main use seem even less viable. Zangoose just doesn't make the cut sadly.
So how to fix it?
Lazy man's answer:
give it extreme Speed.
yeah, let's aid its niche that is no longer a viable niche. That'll work.
No, no it won't. Instead you are setting yourself up for disaster by making a pokemon so specialized that in the right metagame it will destroy it, ALA Blissey and Skarmory in G/S/C. So, not only do we still have a pokemon that isn't viable, but could wreck havok in the wrong environment.
So, with that, we see a need to create a new niche for Zangoose. Any suggestions?
