Entry hazards are one of the highest-leverage mechanics in Pokemon competitive play — a single Stealth Rock sets a 25% tax on every switch your opponent makes for the rest of the match. Learning to set hazards, maintain them, and prevent the opponent from doing the same is a core skill that separates good players from great ones. This guide covers every hazard type available in Pokemon Champions, how damage calculations work, and the removal tools you need in your team.
What Are Entry Hazards?
Entry hazards are field-effect moves that place a persistent condition on one side of the battlefield. Unlike weather or terrain — which affect all active Pokemon — hazards only trigger when a Pokemon switches in on the affected side. That makes hazards a punishment mechanic: the more your opponent swaps, the more chip damage they take.
There are four hazard types in standard Pokemon competitive play, each with a different effect:
| Hazard | Layers | Main Effect | Immune To |
|---|---|---|---|
| Stealth Rock | 1 | Rock-typed chip damage on switch-in | Nothing (hits all) |
| Spikes | 3 | Flat % damage on switch-in | Flying-types, levitating Pokemon |
| Toxic Spikes | 2 | Poison or Badly Poisoned on switch-in | Flying-types, levitating, Steel, Poison |
| Sticky Web | 1 | -1 Speed on switch-in | Flying-types, levitating Pokemon |
All four hazard types can be stacked on the opponent’s side simultaneously, creating a brutal entry tax on every switch. In Pokemon Champions’ early ranked meta (as reported by community players during the June 2026 launch window), Stealth Rock remains the single most common hazard move due to its universal coverage.
Stealth Rock: The Universal Tax
Stealth Rock is the backbone of hazard strategy. It only ever takes one turn to set — one layer, permanent effect — and it hits every Pokemon that switches in regardless of type or levitation.
The damage it deals is calculated based on the switching Pokemon’s Rock-type effectiveness:
| Rock-type Relationship | Damage Taken |
|---|---|
| 4x Resistant (double resist) | 3.125% |
| 2x Resistant | 6.25% |
| Neutral | 12.5% |
| 2x Weak | 25% |
| 4x Weak | 50% |
That 50% chip is devastating. Pokemon with a 4x Rock weakness — certain Fire/Flying, Bug/Flying, and Ice/Flying types — essentially cannot enter the field safely if Stealth Rock is up. A single prior hit and they’re in KO range before the opponent even attacks. This is why hazard removal is mandatory if your team includes Pokemon in those categories.
Stealth Rock is almost always the first hazard you set. It’s efficient, single-layer, and universally threatening.
Spikes: Grounded Chip Damage
Spikes only affect grounded Pokemon (no Flying-type, no Levitate, no Air Balloon). In exchange, they deal flat percentage damage that scales with how many layers are on the field:
| Layers | Damage Dealt |
|---|---|
| 1 layer | 12.5% |
| 2 layers | 16.67% |
| 3 layers | 25% |
Getting three full layers of Spikes up is difficult in practice — each layer requires a separate turn and your opponent will usually try to remove them before layer three. However, even one layer of Spikes combined with Stealth Rock creates a brutal 25% entry tax on any grounded neutral Pokemon (12.5 + 12.5), softening them for your offensive Pokemon to clean up.
Spikes favor team styles that force many switches — weather teams, pivot chains, and stall archetypes. If you’re running a team that can consistently threaten the opponent into switching, each Spikes layer pays dividends repeatedly throughout the match. Check out our weather teams guide to see how hazards synergize with rain and sandstorm chip damage.
Toxic Spikes: Passive Poison Pressure
Toxic Spikes work differently from damage hazards — instead of dealing immediate damage, they inflict a status condition on switch-in:
- 1 layer: Inflicts regular Poison (fixed chip damage each turn, ~12.5% at end of turn)
- 2 layers: Inflicts Badly Poisoned (damage starts at 6.25% and doubles each turn: 6.25% → 12.5% → 25% → 50%…)
Badly Poisoned from two layers of Toxic Spikes is one of the most brutal win conditions in longer matches — a poisoned stall Pokemon becomes a ticking clock. However, Toxic Spikes come with two important weaknesses:
- Poison-types absorb them. If a Poison-type Pokemon switches in on your opponent’s side, it removes Toxic Spikes from the field entirely. This is why many teams that struggle against Toxic Spikes pair a grounded Poison-type in their lineup as a free counter.
- Steel-types and Flying-types are immune. Steel resists Poison, so Toxic Spikes do nothing to them. Flying-types avoid grounded hazards entirely.
Toxic Spikes excel on stall and balance teams that can drag out games. For hyper-offense or teams built around burst damage, the other hazard types usually provide better immediate pressure. See our status moves guide for how Toxic Spikes interact with other poison mechanics.
Sticky Web: Speed Control on Entry
Sticky Web is the most unique hazard — it doesn’t deal any damage. Instead, it lowers the Speed stat of every grounded Pokemon that switches in by one stage (-1 Speed). That -1 drop applies once per Pokemon, not once per switch-in, so switching out and back in doesn’t stack the penalty further.
On paper, -1 Speed sounds modest. In practice, it can:
- Flip speed ties between fast Pokemon (base 100-130 Speed range is extremely common in competitive)
- Allow slower, bulkier attackers to outrun sweepers they normally cannot
- Completely shut down offense built around outspeeding and KO’ing before taking a hit
Sticky Web is most effective in slow, bulky offense archetypes and against teams that rely on naturally fast Pokemon rather than Choice Scarf or Tailwind speed control. Check our speed tiers guide to see which Speed benchmarks Sticky Web disrupts most severely.
Flying-types and levitating Pokemon are immune, making them natural Sticky Web counters. If your team runs Sticky Web, plan for the opponent to pivot their Flying-types in aggressively.
Hazard Stacking: Combining Multiple Hazards
Running all four hazard types simultaneously is called a full hazard stack, and it’s one of the most suffocating strategies in competitive Pokemon. The cumulative entry tax can look like this for a neutral grounded Pokemon:
- Stealth Rock: 12.5% damage
- 2 layers Spikes: 16.67% damage
- 1 layer Toxic Spikes: Badly Poisoned
- Sticky Web: -1 Speed
Even before your opponent attacks, their Pokemon enters the field badly weakened and poisoned. In theory it’s dominant; in practice, maintaining four separate hazard types requires dedicating multiple team slots to setters and leads, leaving less room for offensive threats.
Most competitive teams settle on Stealth Rock plus one other hazard as a practical balance. Stealth Rock + Spikes is the most common combination for pure damage pressure. Stealth Rock + Toxic Spikes suits stall-oriented builds. Early community reports from Pokemon Champions’ ranked ladder (as of June 2026) suggest this two-hazard approach is the dominant pattern, though the meta is still developing.
Hazard Setters: What Makes a Good Lead
A hazard setter is a Pokemon dedicated to getting hazards down in the early turns of a match. The best setters typically share several traits:
- Enough bulk to survive an attack and still move to set the hazard
- Speed control (via Trick Room, priority, or high base Speed) to set up before being KO’d
- Coverage or utility moves beyond the hazard itself, so they’re not a free target once hazards are down
- Priority moves or pivot options to maintain momentum after setting
Bulky Rock-types, Ground-types, and Steel-types traditionally make excellent Stealth Rock users due to their natural bulk and typing. For Spikes, many Pokemon with high Defense stats and access to the move see play. For Sticky Web, fast leads with the move that can threaten the opponent immediately after setting it up are preferred.
That said, which specific Pokemon fill these roles best in Pokemon Champions is still being worked out by the competitive community as of this writing — the meta is fresh and tier placements shift. For up-to-date tier rankings for hazard setters, check our tier list.
Hazard Removal Tools: Rapid Spin, Defog, and Court Change
There are three dedicated hazard removal options in Pokemon Champions, each with a different risk-reward profile.
Rapid Spin is the most efficient single-move removal tool. It clears all entry hazards from your side in one turn — Stealth Rock, all Spikes layers, all Toxic Spikes layers, and Sticky Web — and also raises the user’s Speed by +1 stage after successfully removing hazards. That Speed boost makes Rapid Spin uniquely powerful: you remove the opponent’s hazard investment and gain a speed advantage in the same turn. The main limitation is that it only clears your side. Since Generation 8, Rapid Spin has been able to hit Ghost-types normally, so they can no longer use their typing alone to block the move.
Defog clears all entry hazards from both sides of the field and lowers the target’s evasiveness by one stage as a minor secondary effect. The double-sided clear is a significant trade-off: when you Defog, you remove your own hazards along with the opponent’s. That makes Defog a poor choice if your team relies on Stealth Rock or Spikes. It fits best on defensive teams that don’t run hazards themselves, or in matchups where the opponent’s hazards threaten your team more than your own hazards benefit you.
Court Change is a less common but high-skill option — it swaps all entry hazards, terrain, and side conditions from one side to the other. If your opponent spent three turns setting up Stealth Rock, Spikes, and Toxic Spikes on your side, Court Change flips all of it back to their field. The swing can be match-defining, particularly in mirror matches where both players run hazards. The move requires careful timing: use it against a Defog or Rapid Spin user and they simply remove the returned hazards for free.
Hazard Removal Priority: Which Move to Run?
Your team’s hazard removal choice depends on your archetype:
| Team Style | Recommended Removal | Why |
|---|---|---|
| Offense (no own hazards) | Rapid Spin | Speed boost accelerates tempo |
| Stall / Balance (own hazards) | Rapid Spin | Keeps your hazards intact |
| Defensive (no own hazards) | Defog | Low-risk, clears both sides |
| Pivot-heavy teams | Either | Depends on individual hazard dependency |
| Trick Room teams | Defog | Slower users benefit less from Spin’s Speed boost |
For teams that rely heavily on setup sweepers, removing hazards before bringing in your sweeper is critical. A sweeper that needs three turns to set up cannot afford to enter on Stealth Rock + Spikes for 25%+ chip before it even moves.

Hazards in Singles vs. Doubles
Entry hazards work differently in Singles and Doubles. In Singles, every switch-in triggers hazards, making them a consistent source of chip damage across an entire match. In Doubles, both players have two Pokemon on the field simultaneously and switch far less frequently — hazards still apply, but their impact per game is lower.
In competitive Pokemon Champions Doubles (VGC-style), hazards are less central to the meta than in Singles. Sticky Web sees niche use to flip Speed tiers across the active two-Pokemon field. Stealth Rock and Spikes are occasionally run but take a back seat to direct offensive pressure and support moves. Our Singles vs. Doubles guide goes deeper on how the format difference shapes your whole team strategy.
Building a Hazard-Aware Team
When building your team in Pokemon Champions, ask these questions before finalizing your lineup:
- Who is setting my hazards? If no one on your team can set Stealth Rock, you’re giving your opponent a free tempo advantage in most matchups.
- Who is removing hazards? If you have Pokemon with a Rock-type weakness or Spikes vulnerability, you need Rapid Spin or Defog on at least one teammate.
- Am I immune to Toxic Spikes by accident? A grounded Poison-type absorbs Toxic Spikes, which is a pro if the opponent runs them but means you can’t run Toxic Spikes yourself without losing them to your own Poison-type.
- Does Sticky Web hurt me? If your team is built around fast sweepers (base 110+ Speed), Sticky Web from the opponent can cripple your offense. Include a Flying-type or levitate user as insurance.
These questions apply regardless of which specific Pokemon you’re using. Hazard decisions are structural, not just individual slot choices — they shape how you play the early game and manage momentum throughout the match. A well-structured team from our best teams ranked guide will already account for hazard setting and removal in the lineup design.
FAQ
What are entry hazards in Pokemon Champions? Entry hazards are moves that place damage or debuff effects on your opponent’s side of the field. They trigger every time an opponent switches in a Pokemon, punishing frequent swapping and adding passive chip damage over a match.
Which entry hazard deals the most damage? Three layers of Spikes deal 25% damage to grounded Pokemon on switch-in — the highest raw damage of any single hazard type. Stealth Rock hits harder for rock-weak Pokemon (up to 50% for 4x weakness), but it only scales with type matchup.
What does Stealth Rock do? Stealth Rock scatters sharp stones on the enemy side. When an opponent switches in, those stones deal typeless damage scaled to the Pokemon’s Rock-type weakness: 3.125% for 2x resistant, 6.25% for 1x resistant, 12.5% neutral, 25% for 2x weak, and 50% for 4x weak.
How do Toxic Spikes work? One layer of Toxic Spikes poisons grounded Pokemon on switch-in. A second layer inflicts Badly Poisoned (damage scales each turn). Poison-type Pokemon absorb Toxic Spikes when they switch in, removing the hazard from the field.
What does Sticky Web do? Sticky Web lowers the Speed stat of grounded opposing Pokemon by one stage on switch-in. It doesn’t deal direct damage, but a -1 Speed drop can flip speed ties and shut down fast attackers that rely on outspeeding the field.
How do you remove entry hazards in Pokemon Champions? The main hazard removal moves are Rapid Spin (also raises the user’s Speed by one stage) and Defog (clears hazards on both sides and lowers the target’s evasiveness). Court Change swaps hazards to the opponent’s side. The best option depends on your team’s needs.
What is a hazard setter in competitive play? A hazard setter is a Pokemon whose primary competitive role is to use Stealth Rock, Spikes, Toxic Spikes, or Sticky Web in the early game to put pressure on the opponent’s switches. Bulky leads with priority or pivot moves often fill this role.
Does Rapid Spin remove Stealth Rock? Yes. Rapid Spin clears all entry hazards from your side of the field — Stealth Rock, Spikes (all layers), Toxic Spikes (all layers), and Sticky Web. As of the current competitive mechanics, it also raises the user’s Speed by +1 after clearing.
Can Flying-types avoid entry hazards? Flying-types and Pokemon holding an Air Balloon are immune to Spikes, Toxic Spikes, and Sticky Web since those hazards only affect grounded Pokemon. Stealth Rock, however, hits all Pokemon regardless of typing or levitation.
Should every competitive team in Pokemon Champions run hazards? Not necessarily. Hazards are strongest on bulkier, slower team archetypes (stall, balance, bulky offense) that force many switches. Fast hyper-offense teams sometimes skip hazard setters to maximize immediate power, relying on speed and KOs to win before hazard chip adds up.
