Rain Support Pokémon: What Else the Team Needs

The right rain support Pokémon is rarely another Water attacker. Once the setter and primary attackers are fixed, the remaining slots must create safe entries, control speed and stop Grass, Electric and opposing Water attacks from turning the same weather against the team.

This is a slot audit, not a complete rain-building process or a sweeper ranking. For those jobs, use How to Build Rain Team: A Step-by-Step Process and Best Rain Abusers Worth a Team Slot; here I am only filling the gaps left after that core exists.

Start With the Jobs Your Rain Core Cannot Do

Write down what the setter and two attackers achieve without giving them credit for jobs they perform unreliably. A slow U-turn from Pelipper can bring an attacker in, but Pelipper cannot preserve rain, absorb every hit and repeatedly switch through Stealth Rock at the same time.

Rain lasts five turns including its activation turn, or eight with Damp Rock. Water-type moves receive a 1.5× damage multiplier, Fire-type damage is halved and Swift Swim doubles Speed. Those numbers create pressure, but they do not remove hazards, stop priority or provide an Electric immunity.

My audit uses six questions: who enables safe entry, who controls hazards, who answers Grass attacks, who blocks Electric pressure, who disrupts the opponent and who can win without rain? One Pokémon may cover two jobs. Counting a shaky answer twice is how a team reaches preview with six legal Pokémon and only four functional slots.

Thunder and Hurricane normally have 70% accuracy but bypass accuracy checks in rain. That can make Tornadus useful offensively while it supplies support, yet accuracy is not the same as role compression. A move only earns the slot if it changes a matchup the core was losing.

Singles Support Slots: Hazards, Removal and Momentum

In Smogon singles (OU), I start with the hazard exchange. Fast rain burns turns whenever an attacker must enter through Stealth Rock or Spikes, so the remaining slots often need both progress and removal rather than a passive wall that brings nothing to the matchup.

Great Tusk compresses Stealth Rock, Rapid Spin and Knock Off while giving the team an Electric immunity. Iron Treads offers a Steel typing and Volt Switch instead. The choice depends on which defensive profile the rain core lacks, not on which spinner has the longer list of usable moves.

Corviknight provides Defog and a slow U-turn, which can preserve a frail Swift Swim attacker until the board is clean. It also checks selected Grass-types through its Flying and Steel typing. The cost is low immediate pressure, so I would not pair it with two other slots that only absorb hits.

Gholdengo changes the hazard contest through Good as Gold and its ability to punish removal attempts, but it does not remove hazards itself. Good as Gold grants immunity to status moves, not to secondary effects: Scald can still burn Gholdengo and Thunder can still paralyse it. Tornadus-Therian supplies Defog, Regenerator, Knock Off and U-turn, buying turns while stripping Heavy-Duty Boots or Leftovers. Its Hurricane also bypasses accuracy checks in rain. On fast offense, that removal and momentum can matter more than placing a second hazard.

Format labels matter here. Archaludon was banned from standard SV OU on 17 February 2024 with 75.81% pro-ban support, so I would not recommend it as an OU glue slot. Tera Blast is also banned in current SV OU while Terastallization remains legal through the end of SV.

Doubles Support Slots: Board Control and Speed Control

Doubles asks a different question: how many useful turns does the support mon buy for its partner? Speed control decides more games than raw damage in my experience, so Tailwind is the default plan. Trick Room is a whole build, not a tech slot.

Tornadus combines priority Tailwind, Taunt and Rain Dance through Prankster, with Helping Hand as another support option. Prankster-boosted moves that target an opposing Dark-type fail, so Tornadus cannot use priority Taunt on Incineroar or Kingambit. This restriction does not stop Tailwind or Rain Dance because those moves do not target the opposing Pokémon. Incineroar uses Intimidate, Fake Out and pivoting to reduce immediate pressure. Assault Vest is a meta call rather than the default: it earns its place in a special-heavy room, while Safety Goggles or a recovery item can solve a different board.

Rillaboom brings Grassy Surge, Fake Out and priority pressure, but its terrain weakens common Ground attacks and also heals opposing grounded Pokémon. Amoonguss redirects with Rage Powder, disrupts turns and recovers through Regenerator. Rage Powder does not redirect moves used by Grass-type Pokémon or Pokémon holding Safety Goggles or using Overcoat, so redirection cannot be the only protection plan.

Sinistcha offers Rage Powder, recovery and a Water resistance with a different defensive profile. The same Rage Powder exceptions for Grass-types, Overcoat and Safety Goggles apply. Farigiraf blocks priority through Armor Tail and can use Helping Hand, Icy Wind or Trick Room depending on the ruleset and build. Trick Room only fits a deliberately slow rain mode without Swift Swim; on a standard Swift Swim team, it makes the fastest attackers move last. I think Farigiraf fits rain less automatically than Tornadus; that is a team read, not a proven rule.

Fake Out creates one turn. Tailwind changes four turns including its activation turn if it stays active. Icy Wind adjusts both opposing Speed stats while dealing chip damage. The correct slot depends on whether the core needs one protected attack, a broad Speed advantage or insurance after opposing speed control.

Do not merge VGC doubles, Doubles OU, Pokémon Champions and SV legality into one recommendation. Archaludon remained legal after its May 2024 Doubles OU suspect test despite its singles ban. For official Scarlet/Violet Championship Series events, Regulation Set I replaced Regulation Set F on 1 April 2026, while Pokémon Champions uses a separate ruleset.

Patch Grass, Electric and Water-Mirror Matchups

The common mistake is adding broad coverage instead of assigning switch-in duties. Ground typing denies Electric attacks, which makes Water/Ground Pokémon such as Seismitoad, Swampert, Quagsire and Gastrodon natural candidates for rain. Volt Absorb on Lanturn, Motor Drive and Levitate on Rotom-Wash provide ability-based Electric immunities instead. Lightning Rod also grants an immunity, though its redirection is specific to multi-Pokémon battles.

Flying, Steel, Poison, Fire, Dragon and Bug typing can resist Grass pressure, provided the chosen Pokémon survives the actual secondary coverage. Sap Sipper gives Azumarill, Goodra and Farigiraf a Grass immunity instead. The ability also raises Attack by one stage when triggered, but that boost does not turn every user into a useful physical attacker.

Lightning Rod grants an Electric immunity and raises Special Attack by one stage. Its redirection applies only in multi-Pokémon battles. Storm Drain follows the same format split for single-target Water moves: it redirects in doubles and raises Special Attack by one stage, while singles keeps the Water immunity without redirection.

Rain helps the opponent too. Their Water attacks receive the same 1.5× multiplier, so Gastrodon can turn a rain mirror through Storm Drain. Water Absorb gives Seismitoad, Lanturn, Vaporeon and Clodsire an immunity. Dry Skin does the same for Toxicroak and restores its HP during rain. Rotom-Wash resists Water and can pivot with Volt Switch, though it does not provide a Water immunity.

One defensive slot rarely patches all three matchups cleanly. Great Tusk blocks Electric but this thing folds to strong Grass pressure. Corviknight handles Grass more comfortably but invites Electric attacks. Pair complementary answers instead of claiming that one type chart interaction fixes the team.

Add a Pokémon That Works When Rain Is Gone

I got this wrong first: I treated every dry turn as a temporary failure and filled the team with Pokémon that only functioned under rain. Opposing weather, defensive cycling and stalled turns expose that structure immediately. A five-turn resource cannot be the condition for all six slots to act.

An independent attacker such as Kingambit can threaten progress without weather and punish late-game speed control with priority. Dragonite can also create a separate endgame through priority and defensive utility, while Hurricane bypasses accuracy checks in rain on sets that carry it. Neither belongs on every rain team; the slot earns itself only if it changes the dry-weather matchup.

A bulky pivot is another answer. It eats a hit and clicks U-turn, Volt Switch or Flip Turn, preserving the setter for a later activation. In doubles, priority denial, Fake Out or an alternate Icy Wind mode can stop the team from becoming inert when Tailwind ends or Trick Room goes up.

Preserving Pelipper, Politoed or Kyogre is often better than forcing another boosted attack. Heavy-Duty Boots can reduce Pelipper's entry cost in singles, but Pelipper cannot hold Boots and Damp Rock together. Choosing Boots means rain lasts five turns including its activation turn instead of eight, while Damp Rock leaves Pelipper exposed to hazard damage. Covert Cloak or Focus Sash may protect one critical support action in doubles. Item choice still follows the format and the exact hit the slot must survive.

Choose the Final Slot With a Matchup Checklist

The final slot should pass a preview test before it passes a damage test. I judge the team by the matchup it changes over a 50-game run, not by one clean replay. Usage data can show what players bring, but raw usage cannot prove that the choice wins the matchup.

• Confirm that the Pokémon, move, item and ability are legal in the chosen format and current ruleset.
• Reject the candidate if it creates an excessive shared weakness that the other five slots cannot cover.
• Check whether it preserves the rain setter instead of demanding that the setter absorb another attack.
• Require a safe entry route for at least one primary attacker through pivoting, redirection, disruption or hazard control.
• Name at least one bad matchup that the slot changes; vague extra coverage does not count.
• Keep a function outside rain, such as priority, independent damage, recovery, removal or alternate speed control.

If two candidates pass, test each across the same ladder tier and time window rather than comparing highlight games. Keep the core fixed, record the matchup that caused each loss and avoid copying an EV spread before checking the relevant calc. The smaller sample may still mislead, so treat the result as a working read.
