Sticky Web has always been quite the unique archetype, dropping an opposing Pokémon's speed by 1 stage for free? That does sound quite broken doesn't it? Unfortunately for our 
Bug-type friends, to compensate for the broken effects of this move-- There had to be quite a bit of limiation:
-
Defog was buffed in the same generation, meaning that they weren't nearly as hard to get rid of as it would've been with only 
Rapid Spin.
-Any 
Airborne Pokémon (Possesses the 
Flying-type, is holding an 
Air balloon or possesses the ability 
Levitate) would ignore it, which is pretty big as these Pokémon tend to carry Defog.
-Any Pokémon wearing 
Heavy-Duty Boots is able to ignore entry hazards, including 
Sticky Web.
Due to these numerous limitations, 
Sticky Web Offense never took off as the go-to Hyper Offense-- But rather fell off to near unviability due to the introduction of 
Heavy-Duty Boots in Generation 8. But who cares about that? It's quite the fun archetype to play! Which brings us to the best segway.
Punishing/Preventing 
Defog is quite crucial in SSOU for any Webs Offense, and it just so happens that 
Galarian Zapdos fit this perfectly, as its natural wallbreaking capabilities paired with a 
Defiant boost at the very mild cost of losing evasion is nothing anyone would want to face while it appreciated the speed control provided by 
Sticky Web with it's average speed tier and the insane offensive pressure output by its teammates.
Shuckle is generally seen as the best 
Sticky Web setter. with 
Smearlge being out of the Pokédex for now, it is the only Pokémon who can learn both 
Stealth Rock and 
Sticky Web: This makes it quite the setter paried with 
Galarian Zapdos as it can punish anti-leads like 
Urshifu-Rapid-Strike and 
Melmetal trying to prevent it from setting up, while 
Shuckle provides 
Stealth rock to help out with passive damage output, 
Sticky Web to control speed and occasionally 
Knock Off support and 
Encore for safe switches. I am sure they'll be the best of friends!
