So, this team. Just a little fun offensive team I threw together around this round's core, Archeops/Shiftry. A fairly standard Archeops, though I chose Aqua Tail to help wear down Rhydon so that Magmortar and Klinklang can have easier times, and I don't really want to give a DD/RP Rhydon any completely free turns on this team. A fairly standard Shiftry as well, though I eventually decided on Explosion after I put Swanna on this team. Explosion helps to wear down or KO Gurdurr and Garbodor for Klinklang, Hariyama for both Klinklang and Magmortar, and just pick off most of it's typical checks in general.
As for team member 3, Mesprit is a popular and splashable Pokemon, and on this team it's no exception. Malamar check, sets rocks, and of course most importantly of all, checks Fighting types such as Sawk and Gurdurr. Colbur Berry even allows it to beat things such as Shiftry and Liepard 1v1. Spread is enough speed for Garbodor and rest in bulk, allowing it to check said Pokemon more effectively.
My next choice was AV Magmortar, as it brings a strong special attacker that also checks Lilligant, Vileplume, opposing Fire types, pesky Rotoms for Archeops and the incredibly threatening Ice types in NU that this team was looking a bit weak to. Fairly standard moves, and the speed catches max speed modest Claydol, and also creeping the 240 benchmark of other AV Magmortars to win 1v1 with Earthquake, as well as being faster than opposing Skuntank, Klinklang, and anything else trying to outspeed standard AV Magmortar.
For the 5th member of this team I decided upon Klinklang, as it allows me to beat otherwise very threatening Mega Audino and Musharna. It's obviously able to be taken out by an Audino carrying Fire Blast, but more offensive Audino are much more easily managed with this team than a standard CroDino, which doesn't fear much from the rest of my team, or even a defensive variant which walls everything else. Once again I have crept the 240 benchmark by a few points which is always useful to do, allowing it to do things like potentially pick off opposing AV Magmortar or beat other Klinklang 1v1. Klinklang synergizes well with this team offensively as most of this team shares checks with it that either they or Klinklang can wear down for the other one to win the game. Most notably I'd say is Lanturn, which can loosely check Archeops, check Magmortar, and wall Swanna for days, but because of it's lack of reliable recovery it's never going to be capable of doing half that. Klinklang also just nicely checks a variety of Pokemon such as opposing Archeops and Tauros which have an advantageous match-up vs this team especially if they manage to win a speed tie... which brings me to the final member of my team.
Swanna isn't a very commonly used Pokemon in NU, but for this team it fit what I wanted/needed, giving me a second Water resistance, a check to fighting types, and a decent speed tier to beat out things such as Primeape and Jynx, which could become a lot more annoying otherwise since the only faster Pokemon is Archeops on this team else-wise. It adds a cool little Flying spam aspect to the team as well, potentially helping to wear down certain Flying resistances. Scald and Hurricane provide solid offensive STABs, Scald being chosen over Surf to wear down things with burns. Defog allows me to make Shiftry carry Explosion and covers my weakness to Stealth Rock, also being capable of forcing out/beating most rock setters. Finally I decided on Tailwind over Roost, as in my past experiences Swanna has been too frail to roost on most Pokemon, and it adds a really fun and useful speed control to beat fast opposing Pokemon and allow my some of my slower, powerful Pokemon such as Magmortar to beat a lot of offensive checks/things that would otherwise revenge-kill.
