Battle Factory Guide - Rentals, Swaps & Sample Strategies

I am looking for user submissions for ideal sets that they have used for other players to learn from. If you have a successful run, please submit it in the recommended format at the bottom of this guide! Thank you!

Introduction

The Battle Factory is the rental-team version of the Battle Tower. Instead of bringing your own trained Pokémon, you are given six rental Pokémon, choose three for Level 50 battles, then fight through a seven-trainer challenge.

After each win, you can trade one of your rentals for one of the opponent's Pokémon. That single mechanic changes the whole facility: the best Factory players do not just pick the strongest three Pokémon at the start. They keep improving the team as the run goes on.

Where It Is

The Battle Factory is in Vermilion City. Talk to the receptionist inside to enter the Battle Floor.

The facility also has BP shops, so even failed learning runs can help you work toward useful competitive items.

Rules

The in-game rules are simple:

• You are given six rental Pokémon
• You choose three Pokémon to enter battles
• All three Pokémon must be different
• Their held items must also be different
• Each challenge has seven trainers
• After winning a battle, you may trade one of your Pokémon with the opponent
• If you interrupt a session, you need to save properly or the challenge can be declared invalid

Finishing a seven-trainer challenge rewards Battle Points and gives a Mint Leaf as a challenge reward.

Factory-Specific Mechanics

The Factory is not pure randomness. Your current streak, swap history, and the attendant's pre-battle hint all affect how you should play.

Rental Quality Improves With Swaps

The game tracks how many swaps you have made across the current Factory streak. At the start of a new seven-battle challenge, your rental pool is based on the difficulty of battle 7, then improves by one tier for every six swaps you made before that challenge.

That does not mean you should accept every swap. It means a slightly positive or low-risk swap can be worth taking even if the new Pokémon is only a small upgrade, because enough swaps improve future starting rentals. Bad swaps still lose runs; useful swaps build both the current team and the next draft.

Opponent Hints Matter

Before each battle, the attendant gives information about the next opponent. Early streaks reveal more direct information, such as expected Pokémon. Later streaks give less complete hints, such as a Pokémon using a specific move, a move without the exact user, or the opponent's most common type.

Use that hint before swapping. A replacement that looks good in a vacuum can be wrong if the next opponent's hint points toward a shared weakness, poor speed matchup, or a type your current team already handles.

Thorton Timing

Factory Head Thorton replaces the seventh trainer every third seven-battle run, starting on battle 21 of the streak. Treat that round like a boss check: preserve your cleanest win condition, avoid unnecessary risk in battles 19 and 20, and enter battle 21 with a team that can win without needing perfect matchup luck.

How To Pick Your Starting Three

When you see the six rentals, do not only look for the highest stats. Build a small team with a plan.

A safe starting trio usually has:

1. A reliable lead - fast attacker, bulky status user, or something with few awful matchups
2. A defensive pivot - a Pokémon that can switch into common attacking types and stop one bad matchup from ending the run
3. A win condition - setup sweeper, Choice attacker, or strong cleaner that can finish weakened teams

The best rental is not always the flashiest one. A slightly weaker Pokémon with accurate STAB, useful coverage, and a good item is often better than a stronger Pokémon with risky moves or a narrow matchup spread.

In 3v3, role compression is premium. A Pokémon that is both bulky and threatening is often better than a pure wall, because every slot needs to help you make progress. Prioritize rentals that can do two jobs: Intimidate plus damage, screens plus Volt Switch, recovery plus setup, priority plus wallbreaking, or status plus reliable attacks.

Rental Evaluation Checklist

Use this quick checklist before locking in your three:

Tank, Bulk, And Setup Evaluation

Bulk is only valuable if it buys useful turns. Do not treat every high-defense rental as a safe pick.

Good Tanks

Good tanks take a hit and immediately change the battle state. They threaten a KO, spread status, set screens, force a switch, heal reliably, or create a setup chance for a teammate.

Look for:

• Recovery plus real attacking coverage
• Intimidate, good resistances, or immunity abilities
• Scald, Thunder Wave, Toxic, Will-O-Wisp, Encore, Taunt, or phazing
• Leftovers, Eviolite, Sitrus Berry, or another item that extends useful turns
• Enough damage to stop opposing setup sweepers from using it as free bait

Bad Bulk

A bulky rental is risky when it only absorbs damage. In long streaks, a passive wall can invite setup, lose to critical hits, run out of PP, or leave you dependent on one teammate to actually win.

Be skeptical of:

• Walls with no recovery
• Walls with recovery but no pressure
• Toxic or Perish Song sets with no backup damage plan
• Defensive Pokémon that stack a weakness your team already has
• Slow tanks that cannot survive the common super effective hits aimed at them

Setup Discipline

Setup is one of the best ways to win Factory battles, but it is also one of the easiest ways to throw a streak. A setup sweeper is worth more when it needs one boost to win, has natural bulk or priority, and still functions before boosting.

Set up when:

• Screens, Encore, paralysis, sleep, or a forced switch creates a real free turn
• The opponent is locked into or likely to repeat a resisted move
• One boost lets you outspeed or KO the remaining threats
• Your backup attacker can still clean up if the setup attempt fails

Do not set up when you have not checked for status, phazing, priority, super effective coverage, or a faster revenge killer. A greedy boost is how good Factory teams lose to average rentals.

When To Swap

After each win, ask whether the opponent's Pokémon improves your actual team, not whether it was annoying to fight.

Usually Swap When

• The opponent has a clear upgrade for one of your weakest rentals
• The new Pokémon fixes a shared weakness your team has shown
• The new set gives you speed control, priority, status, or better defensive coverage
• Your current Pokémon only won because of matchup luck and is unlikely to keep helping
• The swap is at least a small upgrade and helps build toward the next rental-tier bump
• The next-opponent hint makes one of your current Pokémon look exposed

Usually Keep Your Team When

• Your current three already cover each other's weaknesses
• The opponent's Pokémon is strong but duplicates a role you already have
• The swap would leave you without an answer to a common type
• The new Pokémon relies on low-accuracy moves, awkward setup, or an item your team cannot use well
• You would give up your only safe answer to the next-opponent hint

A good rule: swap to make the next battle safer, not to reward the last battle's MVP. The best swap is often boring: it removes a dead slot, protects a needed matchup, and nudges your long-term swap count without breaking the team.

Sample Rental Team Shapes

Because rentals are randomized, these are templates rather than guaranteed teams. Use them to recognize good groups when the Factory offers them.

Safe Balance

How it plays: lead with the Pokémon that gives the fewest bad openings, pivot out of dangerous matchups, then preserve your cleaner until the opponent's team is chipped.

Setup Support

How it plays: do not boost blindly on turn one. First identify the opponent's status moves, phazing, priority, and super effective coverage. Set up only when the support slot has made the turn safe.

Bulky Control

How it plays: win by keeping games stable. This shape is especially good when the opening rentals do not offer a clean sweeper but do offer several sturdy sets.

Tempo Offense

How it plays: avoid giving the opponent free turns. This shape is good when the rental pool offers strong attackers but no true wall. You are not trying to switch forever; you are trying to trade favorably and keep the last matchup under control.

Sample Decision Walkthrough

Suppose your six rentals include:

• A fast attacker with accurate STAB, priority, and mediocre bulk
• A bulky Water with recovery, Scald, and Toxic
• A screen setter with Volt Switch
• A slow wall with recovery but no real damage
• A Swords Dance sweeper with weak coverage before boosting
• A Choice attacker with two strong moves and two bad lock-in moves

The best starting three are usually the fast attacker, bulky Water, and screen setter. That gives you speed, a safe pivot, status pressure, and a way to create turns. The slow wall is tempting, but if it cannot pressure setup or status-immune foes, it may only delay losses. The Swords Dance user is worth taking only if the screen setter makes setup reliable or the rest of the pool lacks a cleaner.

After battle 1, imagine the opponent offers a stronger attacker, but your next hint says the opponent favors Electric-type Pokémon. If your bulky Water is your weakest slot, swapping it out might still be correct. If it is your only answer to Ground coverage or your only status spreader, the stronger attacker may be a trap. Judge the swap against the next battle, not against the battle you just survived.

Common Factory Mistakes

• Picking three attackers with the same weakness. You may win the first battle quickly, then lose as soon as the Factory finds the shared weakness.
• Overvaluing legendary-looking stats. Moves, item, ability, and role fit matter more than raw stats.
• Swapping after every win. Swaps are useful, but unnecessary swaps can break a team that was already working.
• Never swapping. Swap count matters over a streak. Passing every small upgrade can leave future rental pools worse than they need to be.
• Ignoring accuracy. Long streaks punish moves that miss at the wrong time.
• Keeping a dead slot too long. If a rental has done nothing for multiple battles, look hard for a replacement.
• Calling all bulk good bulk. A wall that cannot heal, threaten, status, or support can become setup bait.
• Boosting because you can, not because you should. Setup only matters if the boosted Pokémon can actually finish the matchup.

Player-Submitted Strategy Format

If you have a tried-and-tested Factory run, submit it with enough detail that other players can learn from it.

Recommended format:

Notes for other players:

For Factory submissions, swaps are often more useful than a final team screenshot. The story of how the team improved is what helps other players emulate the run.

Quick Advice

• Start with the most complete three-Pokémon core, not the three strongest individual rentals
• Keep at least one answer to fast attackers
• Value tanks that make progress over walls that only sit there
• Use the next-opponent hint before judging swaps
• Prefer accurate moves during long streak attempts
• Swap for role coverage, not novelty
• Take low-risk useful swaps often enough to improve future rental quality
• If a loss feels unavoidable, note the shared weakness that caused it and draft around that next time
