Introduction to Entry Hazard Stacking
Entry Hazard Stacking Overall:Introduction to Entry Hazard Stacking

Entry Hazard Stacking is one of the one the best and most popular playstyles in PU, especially after the gain of viable setters such as Probopass from tier shifts. The name of the playstyle explains how it works: it is based on stacking layers of Spikes / Toxic Spikes and Stealth Rock, which allow the user to pressure and wear down foes every time they switch in, while still managing entry hazard control by carrying a Defog or Rapid Spin user such as Pelipper or Armaldo. Stacking up entry hazards and wearing down foes will eventually create opportunities for plenty offensive Pokemon in PU to clean up or sweep the opposing team, making this a lethal playstyle even after the ban of powerhouses such as Tauros and Kecleon
Going into roles and the building an Hazard Stacking team, your team will follow most of the time a pattern similiar to this one: Spikes Setter / Stealth Rock Setter / Defiant User / Spinblocker / Defog - Rapid Spin user or Revengekiller / Sweeper-Cleaner. This classic pattern of a simple Hazard Stacking team can be subject to changes depending user's preferences and style of play, one example adding a Sticky Web user to make even more easy the job of the Sweeper-Cleaner, or replacing the Spinblocker with another win condition to follow a more offensive build path.
These are by no means the only viable Entry Hazard setters in PU
Dwebble:

Dwebble returned with a bang as a viable and decent Entry Hazards setter acting as a Suicide Lead on Hyper Offense thanks to the release of Custap Berry, contesting Whirlipede's spot. Its main niche consists in being able to place both Stealth Rock and Spikes, and Custap Berry + Sturdy make it more easy, granting at least Stealth Rock and a layer of Spikes from the start, which is really good, still not being Sturdy dependant if you run Endure, which makes Dwebble survive an hit anyway even if the Sturdy gets broken.

Along with Toxic Spikes / Spikes setters there is a Stealth Rock setter to keep up the pressure on ground immunities, there are really a lot of viable pokémons that can fullfill this role, but the most seen at the moment now are:

Probopass is the relatively new guy dropped from NU, and in my opinion this is one of the best drops for the tier. With it PU gains a really good Pivot capable of setting Rocks on the field, having a great bulk and trapping Steels with Magnet Pull. Probopass also has a good coverage that can able him to run different sets making him fit in many teams' strategies so I highly suggest to you using it.

Carracosta isn't really preferred on Offensive Teams since it is really slow paced and even if it has a decent coverage, it can't hit hard without Offensive Investments. Still it provides to teams such as Balanced and Stalls a wall of meat thanks to its Bulk and Solid Rock, other than its four typing resistances that has many opportunities to set up Stealth Rock other than checking the scary Sneasel and other Strong Physical Attackers.

Golem isn't really seen lately, but it's still a decent Stealth Rock setter on Hyper Offense teams thanks to its High Base Atk stat and Sturdy, which makes it set up Stealth Rock safely most of the time other than making Golem run purely Offensive sets despite its low speed such as the Weakness Policy+ 3 Atks and variants such as the Custap Berry + Explosion to catch the opponent off guard.
Weakness Policy + 3 Atks
Golem @ Weakness Policy

Piloswine is one of the most reliable Stealth Rock setters in the tier that works on both Offensive and Defensive teams, differently from Carracosta and Golem, thanks to its great bulk with Eviolite along with its Typing and Thick Fat which makes it able to check Electric-types and tank Ice- and Fire-type moves really well, still carrying Offensive Potential to at least KO an enemy' pokemon if played properly.

Clefairy is actually one of the best choices as a Stealth Rock user for defensively-oriented teams, as with Eviolite and a Special Defense investment, it is able to tank special hits with ease, even from strong attackers such as Ninetales and Simipour, therefore coming in hand often nowadays, but it is able to also provide even more utility, thanks to the access to moves such as Thunder Wave, Knock Off and Healing Wish, making it a solid wall but also not a complete sitting duck.

Sticky Web Users:


Sticky Web could be used in an Hazard Stacking team since they have a good synergy with Defiant Users and Spinblockers other than making more easy cleaning and revengekilling the enemy' Pokemon for slow paced teams. Leavanny

Of course you have to punish your opponent if he defogs/Rapid Spins away all of your precious stacks of Toxic Spikes / Spikes or Stealth Rock from the field so most of the time you will usually fit into the team a Defiant user. There are only really two viable Defiant users in the tier: Pawniard

Spinblockers will prevent Entry Hazards from being removed by Rapid Spin users, which is mandatory in a PU Hazard Stacking Team since there are a lot of viable Rapid Spin users out there. The best Spinblocker is Misdreavus

Things to consider when building an Hazard Stacking team:
Entry hazard setters are obviously mandatory when building an Hazard Stacking team, along with at least a spinblocker or defiant user to preserve your hazards or put pressure on the enemy's defog user. There can be made some combinations formed by Pokemon I mentioned above, from the one with Poliwrath









Team Examples:
We have pretty good examples of hazard stacking offense teams on the subforum already, on the Sample Teams thread, including mine, and we know it's a pretty consistent strategy to rely on, so give a look at them since they include some informations and building phase, which can be useful if you are looking forward to build one by yourself.
TONE114 's Hazard Stack HO
Raiza. 's Hazard Stacking Bulky Offense
Kushalos 's Venipede Spikes Offense
Mine had Kecleon but replace it with Kadabra, it works fine with it anyway.
Hazard Stacking is a really good and fun playstyle at the moment, being a Low Risk/High Reward typology of team since it's really accomplishing and can really be lethal and lead to constant victories if played well so I highly recommend you trying it either building a team or trying out one of these I posted. If there is anything about Hazard Stacking in PU that you want to ask or discuss, or if you just want to share a replay, than this is the place to do it.
