'Twas the night before Christmas, when all through the house
Not a creature was stirring, not even a mouse;
The stockings were hung by the chimney with care,
In hopes that St. Nicholas soon would be there;
The children were nestled all snug in their beds;
While visions of sugar-plums danced in their heads;
shnowshner was waiting for a team with Equilibra and Roaring Moon,
and to that, in his stocking, good old St. Nick gifted him this boon;
Okay, I'm dropping the rhyming for the team explanation, because honestly I don't think I can actually manage to pull that off. As mentioned prior, this team is built around Roaring Moon + Equilibra. This honestly wasn't a super hard core to work with, as Roaring Moon is broken and Equilibra is already a fairly solid glue mon, and while I could have easily just made Sun to fulfill the request, I decided that it would be a lot more fun to just do regular balance or bulky offense instead.
Hisuian Samurott serves as my main (or I guess only) way of setting hazards and as a mon that can lure in Fairy-types for Equilibra. I was considering going with the Swords Dance set for a bit to serve as a secondary wincon, but I decided later on that an Assault Vest set would work better here to create a nice Specially Defensive core with Equilibra. Skeledirge's role to mainly soak up physical attacks, serve as a counter to Hemogoblin (Which most of the team struggles with), and act a bit as a secondary win condition in the event Roaring Moon is unable to sweep. Rillaboom acts as a wallbreaker and a form of speed control, and synergizes nicely with the rest of the team by providing Grassy Terrain support and dealing with bothersome Water-types such as Cresciedon and Krilowatt. Lastly, Zapdos provides paralysis support in the form of Static, acts a special wallbreaker, and gives the team a more reliable answer to Venomicon.
Regarding sets, most of the stuff here is fairly standard, but there are a couple of things that stand out a bit. While I decided not to deviate from the norm for most of the Tera Types here, Tera Fighting Zapdos was an exception. I wanted it to be able to act as an emergency Kingambit check, so a Tera-type that resisted Dark was mandatory, while at the same time, I really didn't want to give Zapdos a Tera Type that would be weak to any of the main moves you see Venomicon running. As a bit of an added bonus, Tera Fighting does allow Zapdos to check Tera Flying Iron Boulder, since Thunderbolt OHKOs 75% of the time with one layer of spikes. As for EV spreads, the spread on Skeledirge allows it to avoid a 2HKO from Tera Ground Hemobolin's Tera Blast, while nothing else here really needs explaining.
In terms of stuff the team struggles with, fast physical attackers that have a way of getting past Skeledirge are going to be a pain in the ass to deal with for obvious reasons. A lot of times, if you are up against something like an opposing Roaring Moon or SD Iron Valiant, you may end up finding yourself in a situation were you are forced to prematurely Skeledirge so that your entire team doesn't get swept. There's definitely some things that can be optimized here, as the matchup into Hyper Offense, while not unwinnable, doesn't feel great. Still though, the team preforms fairly well into most balance and bulky offense structures, and I've had a fair amount of fun using it as well.
