Ok, so one thing I noticed during team testing on Showdown! was your chronic Rock and Ice weaknesses. Once Swellow is down, you're weak to a bunch of fast threats like Braviary and such. Zangoose OHKO'es your Armaldo with Close Combat, your only way to resist to his deadly Facade. But your team has a terrible weakness to Cincinno who can spam Rock Blast and sweep your whole team. A Scarfed Braviary (It's popular these days) can spam Brave Bird to sweep your whole team or the new version of Braviary, the one with Brave Bird and Life Orb paired with Roost to shrug off all the damage. Zangoose can just spam Facade and his other moves when desired to sweep your team. There is also Shell Smash Gorebyss who can, when well played, sweep your team as well. For the rate, i'll start with my favorite member of the team, Haunter.
Your Haunter set is very strong, but I don't know what HP Ice is doing there. Maybe it's for the Ground type switch-ins, I dunno. All I know is that HP Ground is more well suited to hit Probopass, Bastiodon and Skuntank more harder. With Sludge Bomb and Shadow Ball, they provide perfect neutral coverage in NU. Also, switch those 4 last EVs from Special Defense to HP. He won't taking a Special hit anyways. Neither a Physical one.
Ok, on to your lead, Armaldo. No idea why Iron Defense is here. So you have two Pokemon that are weak to S-Rock. I don't know for you but for me, that's enough to go fetch for a Rapid Spinner. Armaldo can utilize Rapid Spin very well and we will be replacing Iron Defense for it. Since Iron Defense is out, I am guessing we'll also change your EV Spread and Nature. I prefer Impish Nature and 252 HP / 252 Def / 4 SDef but you can keep yours. Also, switch Stone Edge for Rock Blast as it can break through Subs and Stone Edge's shaky accuracy is not reliable.
Ok, Marowak's turn. So I don't like your last moveslot choice, neither the fact that you have Swords Dance on him. Sure, Swords Dance is awesome but still, you have the risk the setup. If I were you, i'd switch it out for Stone Edge and replace ThunderPunch for Double-Edge. With Rock Head preventing the recoil, you can do terrifying damage to Pokemon who resist the EdgeQuake combo. I know I suggested Stone Edge here and told you not to take it on Armaldo but it's a matter of Pokemon as Rock Blast is more suited to Armaldo.
Gorebyss is almost perfect as i'd suggest HP Electric over Substitute for something to hit Water type who resist Ice Beam and Surf. You could also try HP Grass as Seismitoad is getting a bit more popular these days.
On to Leavanny. I'm not very fond of him or any other Bug types in NU, except for Butterfree. Your team has problems with Ice types so I will be replacing Leavanny with Sawk, who can easily fix your Ice problem. Choose between scarf and Band but I recommend Band as you already have two extremely fast Pokemon in Swellow and Haunter.
Sawk @ Choice Band
Trait: Sturdy
EVs: 252 Atk / 252 Spd / 4 HP
Adamant Nature (+Atk, -SAtk)
- Close Combat
- Stone Edge
- Earthquake
- Ice Punch
Awesome Banded set with Adamant so you don't lose any power or..
Sawk (M) @ Choice Scarf
Trait: Sturdy
EVs: 252 Atk / 4 Def / 252 Spd
Jolly Nature (+Spd, -SAtk)
- Close Combat
- Earthquake
- Stone Edge
- Ice Punch
On to your last Pokemon, Swellow. As I mentioned before, your team is weak to a bunch of threats such as Cincinno so i'm suggesting.... Braviary!
Braviary (M) @ Choice Scarf
Trait: Defiant
EVs: 252 Atk / 4 Def / 252 Spd
Jolly Nature (+Spd, -SAtk)
- Return
- U-turn
- Superpower
- Brave Bird
Basic Braviary who allows you to revenge kill all the threats that I mentioned. He is such an underrated Scarfer..... Anyways, you can figure this set out by yourself.
Ok, this is the end of my rate. Hope I helped you!
