Audino should go down cause it's outclassed by licki and only has regenerator and a slow encore to save it which licki makes up for with a better bulk and phazing. I'm not saying licki is always better, but most of the time.
Beheeyem has nothing to do in the same tier as gardy, trick room is just not a good strategy in NU, I've never seen it work. Other than that beheeyem is either outclassed by gardy or mushy (and maybe even duosion which is currently in C
zebra to B because our tier leader in zeb. No but seriously, zebstirka has amazing coverage and an extremly strategic speed. It's at least as good as electabuzz if not better.
Also, why is shiftry B ? I won't start debating about it now, but I don't even get what makes it B worthy. It was already pretty bad in last meta and now with 3 more great mons that outspeed and ohko it I'd definately see it as C material.
I don't know, those seem like viable advantages to consider Audino over Lickilicky, especially in a hazard-infested metagame. I've always compared the two as equals, neither one being outright better than the other, since they have notable advantages over the other.
Beheeyem stands out amongst its Psychic brethren with its immense power and being one of the very few I've seen to use Trick Room even remotely well (mostly because TR works best if you set it up for yourself and not others), only other notable examples would be Lampent or something. Between Analytic (with Nasty Plot if you wish!) to own defensive teams with boosted assaults, and Trick Room to roll over offensive teams, Beheeyem holds this unique niche no other pokemon can perform. Thunderbolt is also a plus, allowing it to threaten Mandibuzz which Musharna and Duosion have no hope of accomplishing. While it lacks Focus Blast and/or additional STAB, Beheeyem can still give Gardevoir and Jynx competition by not caring about its speed, permitting investment in bulk that either builds up resistance to priority moves while under TR or utilize Analytic as much as possible outside TR. it's mostly the power aspect of Beheeyem that is most appealing about it.
Amazing coverage + strategic speed
- great power = limited potential. This basically limits Zeb to weakened targets or opponents vulnerable to SE hits. Electric/Fire/Grass may sport good neutral coverage as Eel has pointed out, but when it comes to hitting neutrally, Zebstrika misses out on a lot of opponents because 80 base Special Attack for an Electric really doesn't make it all that great (Electrode :[ ), especially given its fraility.
I think Shiftry made it into B because of how it can harass nearly every wall in NU due to its coverage and power, Shiftry can even use its ability Early Bird to either absorb Sleep to activate Sleep Clause (unlike Vital Spirit) while potentially being able to spring right back up to fight, or use Rest to shrug off any status and damage defensive teams throw at it and wake up after just one turn. Unfortunately a new face in Mandibuzz pretty much put it in its place. Having STAB Sucker Punch makes Shiftry useful against offense as well, but Sucker Punch is a pretty big gamble to rely on, especially when it's a matter of life and death against Jynx (luckily Early Bird may possibly salvage the situation).
There was talk about Muk earlier, and I have to say that it's the Poison-type arguably least affected by the drop of Junx (in fact the decrease in usage of other Psychics benefitted it greatly). The big reason for this is its priority move, Shadow Sneak. Most other Poison-types have access to Sucker Punch which can lay a huge dent in Gardevoir, but Muk's Shadow Sneak isn't enough. Now, Sucker Punch users are now the ones who are unreliable in the face of a Jynx, who commonly Lovely Kiss to counter the move, but Muk's Shadow Sneak lands a solid hit on Jynx every time, no questions asked. Also, there is its trademark tounch, which can poison foes upon making contact with them. What this means is that Muk's Poison Jab has an absurdly high chance to poison, and its elemental punch can inflict poison as well as its respective status. I myself, having used Muk before, find myself struggling to build up enough Curses
before the RU drops, much less now; but its Choice Band set utterly wrecks, I used Gunk Shot on it because it seriously hits like a truck (OHKOIng Eelektross), while relying on its good special bulk to come out on top.
