Shuckle is one of my favorite pokemon, so I want to build a team around him. What pokemon make good teammates? The shuckle I want to run has sticky web, stealth rock, toxic, knock off holding leftovers.
Hello and welcome to Smogon!
Shuckle is good because of its almost exclusive access to Sticky Web, and its ability to come back later in the game, while Galvantula (another web setter) is usually brought down to its Sash on the first turn because of its frailty.
Sticky Web teams usually use Pokémon that are very powerful, but are slower than some opponents. A good example of this is Bisharp-- not only does it threaten many opponents with its high Attack stat and access to Swords Dance, but it can discourage people Defogging away your Sticky Webs due to its ability.
Of course, you'll need a check to Flying-type and Levitating Pokémon, as they aren't affected by Sticky Web. Mega Diancie sounds like a good fit here, as it can easily beat the likes of Lati@s, Talonflame, Mega Pinsir, and Tornadus-T (although Landorus-T could still be a problem).
From there, you have a lot of options, like Breloom (which I highly recommend to beat opposing Bisharp, which get a +2 boost due to Sticky Web), Starmie (takes out opposing hazards), and your own Ghost-type to block opposing Rapid Spins. (Beware: Gengar is very bad at this). Be sure to throw in something that can reliably check Landorus-T, like maybe a Life Orb HP Fire + Roost + Ice Beam + Dragon Claw/Pulse Kyurem-B, which can beat Scizor as well.
A fun Pokémon to use on Sticky Web teams is Choice Band Tyrantrum. Click Head Smash and literally nothing can switch in. It also greatly improves this team's Stall matchup.
I'd recommend changing your Shuckle set up a bit. Toxic isn't very good in OU because the few Pokémon that mind it usually have a Chansey backing them up. Try this set instead:
Shuckle
@ Chesto Berry
Ability: Sturdy
EVs: 252 HP / 252 Def / 4 SpD
Relaxed Nature (+Def, -SpA)
-Sticky Web
-Stealth Rock
-Rest
-Knock Off
This set allows Shuckle to return to the field and set up more webs, even if the opponent has their own Stealth Rocks up.
At this point, a sample team might consist of Shuckle/Mega Diancie/Breloom/Tyrantrum/Kyurem-B/Bisharp. Obviously, this team probably won't be very good because I just made it up, but hopefully it should be a good starting point. Good luck!
