Pokemon who'd benefit from unique abilities

I feel that some good poison types could benefit from corrosion Dragalge, Ariados , Swolot ... i can go on there are a good deal of poison types that could take that ability well....​

I could go on and on about that .​

 

I would LOVE LOVE LOVE for more Pokémon to have the ability Illusion. I love Zoroark and zorua with everything I got, but when it's the only Pokémon with it's ability; everyone knows what zoroark is there for. If they were to give it to other Pokémon, I would hope it'd be a secondary or hidden ability though on a mon who already has a decent ability so the mind games can deepen.

Outside of that.... Alolan Raichu and Volt absorb.... why it can't keep it's Kanto counterpart's hidden ability is beyond me, but I feel like it'd be so good to have it be able to run both sets.

 

I think starters should have special ones since they all have Blaze, Torrent, and overgrow. They are rare Pokémon who we work hard to raise, least they can do is make it possible to at least get the HA easily.

 

Zen Mode and Shields Down are similar enough, yet for different Pokémon, so they are clearly unique. Disguise is also awesome. Can't wait to see it put on an event Pokémon.

 

Perhaps Pixilate on any physical attacking Fairy types? I know Mega Altaria can run D-Dance and Return.

 

I've seen some people note how Toxapex and Salazzle would really benefit from the other's signature ability more than their own, with Toxapex being a wall who'd really like to be able to poison anything but has measly offensive stats, and Salazzle a wall-breaker who's very frail and thus shouldn't be spending time trying to Toxic things and would instead fare better critting everything it managed to poison with Sludge Wave. I'd love for Salazzle to get Merciless as an extra ability, and while I think Toxapex is good enough as is and don't like it as much as Salazzle, I guess it'd be neato for it to get Corrosion too.

Merciless is something I'd personally love to see some pogies I'm a big fan of get, like Toxicroak. Or even Crobat, I do remember rumors of the latter getting it surfacing for a short while.
