I built this team after a few days of suspect laddering, after trying to use only fun teams and losing a lot. Therefore I thought, "what is the most try hard team I could possibly build". That's how this team came into existence. I've given this team to several people, I think a few people even got reqs with it. There are like 20 versions of this team with each of these pokemon having different sets/natures, one person I even told to use Sneasel over Aurorus which may overall be the better choice, but these are the sets I used for the majority of my laddering experience. I began with Smeargle as my suicide lead and webs layer. Web's provide Lee the necessary speed boost to out speed a lot of RU, which is what I originally wanted to make the team around. I also realized how great Venomoth is under webs, as Sticky Webs eliminates a lot of its revenge killers and doesn't make it need to rely on getting up a Quiver Dance as much. Fletchinder helps me vs opposing Venomoth and revenge kills a lot, web's also allows Fletchinder to be able to wisp things it otherwise wouldn't be able to like Durant to support the team so Venomoth can set up on them. Scarf Flygon serves as a check for things like Scarf Delphox which can be very annoying. Aurorus was added as the last mon, mainly because I wanted a Fletchinder check that didn't give Flygon a free switch in. I was never sure what I wanted as its last move slot, Ice Shard would have been great but Game Freak is ass. Calm Mind helps a lot vs stall, Rock Polish lets it out speed most scarfers and since Smeargle doesn't often have a chance to set up both hazards rocks is an ok choice. Overall if played will this team is terrifying, the power of Moth + Fletch is insane vs most teams.
EDIT: So since Venomoth has left I was forced to rework the team. The team still centralizes around using Sticky Webs to aid Pokemon in avoiding revenge killing and wreckin' teams, but now includes two new members: Samurott and Sneasel. I mentioned in the original post that Sneasel was way better than Aurorus on this team, so now that moth is gone I can't farm free wins based off how broken moth was. Sneasel checks most psychic types as well as actually beats Flygon, marking off one massive threat to the original team. I decided to get over my fear of Fletchinder since it really only sets up on Flygon and remove of my flying resist. Instead I feel pretty confident in Samurott to revenge kill it with Aqua Jet. Speaking of Sam, I added it as an offensive Sneasel check under webs, its ability to take on most water types and Aqua Jet to put Fletchinder in range of my own Fletch and Lee's punch. It has speed for Sneasel under webs, and the rest in attack for more Aqua Jet power. Band>Scarf Flygon to break waters and I have hella priority. Still heat though not as much :(
