How to build a balanced team in 60 seconds

  1. Pick your game above so only legal Pokémon, moves and the right type chart are used.
  2. Add your must-have Pokémon. Tap a slot, type a few letters (English, 中文, 日本語, Français, Deutsch, Español or 한국어 all work) and press Enter.
  3. Read the red rows in the Weaknesses tab — a type is a problem when three or more Pokémon are weak to it and nothing resists it.
  4. Use Smart picks. The suggestions under your team are ranked by how much they reduce shared weaknesses and fill coverage gaps.
  5. Check Coverage and Threats, add moves, then Share the link or export to Showdown.

FAQ

Which Pokémon can I use in Ruby, Sapphire, Emerald, FireRed & LeafGreen?

The picker shows the 389 Pokémon and forms available in Ruby, Sapphire, Emerald, FireRed & LeafGreen. Switch to National Dex to plan with every Pokémon.

Does the builder use the right type chart for this generation?

Yes — it uses the Gen 2–5 type chart (no Fairy type, Steel still resists Ghost and Dark).

How does the team builder calculate weaknesses?

For each of the 18 attacking types it multiplies the type-chart values against every Pokémon's typing, then applies abilities that change incoming damage — Levitate, Flash Fire, Water Absorb, Volt Absorb, Storm Drain, Sap Sipper, Thick Fat, Heatproof, Purifying Salt, Filter and more. A type is flagged red when three or more of your Pokémon are weak to it and at most one resists it.

Can I import and export Pokémon Showdown teams?

Yes. Paste any Showdown or PokéPaste text into Import and the builder keeps nicknames, items, abilities, Tera Types, EVs, IVs, natures, levels and moves. Export gives you text you can paste straight back into Showdown's Teambuilder.

How do I share my team?

Press Share to copy a link — the whole team is encoded in the URL, so anyone who opens it sees the same six Pokémon, sets and analysis. Image creates a 1200×675 team card that is ready for Reddit, Discord or X.

Is it free? Do I need an account?

It is completely free and has no sign-up. Teams are saved in your browser for each game and in the share link; nothing is uploaded.
