Alright, I'm closing this thread tomorrow, so be sure to get your sets in if you haven't already! Also keep in mind that discussions about Sneasel are permitted and encouraged until when I close Voting near the mid-end of this week and put up a different Victim,
so don't be afraid to voice your opinion!
Right now, I'm going to be mainstream and say that
Goddess Briyella's Snubbull set is probably the best answer to Sneasel so far with Growlithe coming in close second. Although they both solidly handle Sneasel in their own ways, I like Briyella's Snubbull the best because it
is so fucking annoying is a very solid Pokemon defensively. Snubbull can easily tank a Knock Off and Ice Punch (though it will be damaged to the point where it can't really do anything else for the rest of the match) but OHKO with Play Rough. The cool thing about Snubbull is that it retains the focus of countering Sneasel but doesn't sacrifice other important aspects- such as offensive presence, momentum, and coverage- in order to do so, making it a great contender for this week's poll. Snubbull's Play Rough hits pretty hard and is certain to ward off any physical based attackers in fright of -Atk, and Thunder Wave also makes Snubbull really hard to switch into. Not only does it counter Sneasel adequately, it also doesn't have to sacrifice offensive presence in the process.
Following along those lines,
unitard's Growlithe is also a great answer. It is even more reliable at countering Sneasel than Snubbull (except when Stealth Rock is up) and can easily threaten it out. Plus, it can recover off the damage, helping it last longer so it can continuously and reliably deal with Sneasel when necessary, which is
extremely important since Sneasel is a very fluid Pokemon that tends to switch in and out a lot. Growlithe doesn't drop offensive power either; Flare Blitz hits like a truck and goes relatively unresisted in the Little Cup tier, making it a very prominent attacker. Will-o-Wisp is also a great move to cripple not only Sneasel if it is foolish enough to stay in but also anything that is going to try to switch into Growlithe, such as the physical Rock- and Ground-types that are common in the tier. Switching Growlithe into Sneasel doesn't take much thought, won't have much consequence, reliably deals with the threat, and grabs momentum in the process. Very nice submission.
Remember, we're looking for Pokemon that can both reliably counter the Victim
as well as hold its ground in the metagame either offensively or defensively against other common threats besides the Victim. The better the submissions are at those two things, the more likely they will get voted for!
