This guide demonstrates the simplest ways to use Auto-Legality Mod (ALM) to generate legal Pokémon using Showdown sets. Showdown sets are used by Pokémon Showdown to communicate basic competitive information about a Pokémon.
Creating Showdown SetsShowdown sets are the easiest method to use ALM. It is highly recommended that you learn to create a Showdown set.
Since Legends: Arceus is not supported on Showdown, you will have to adapt a set from the other formats. You can use Alpha: Yes to request that a Pokémon be generated as an alpha.
Navigate to the Pokémon Showdown Teambuilder page.
Create a "New Team" and set the format to "Ubers" or "Anything Goes".
Click on "Add Pokémon" and start building your sets. Click on "Validate" afterwards to ensure that your Pokémon are legal.
Click on "Import/Export" and copy the sets you want to import into ALM.
Here is a video of these steps for creating, validating, and exporting a set:
Importing Showdown SetsThere are several ways to import a Showdown set into ALM. If you are importing only one Pokémon, it will be added to the active Pokémon panel on the left. If you are importing multiple sets at once, they will be added to the active box.
Import with Auto-Legality Mod: Click on Tools > Auto-Legality Mod > Import with Auto-Legality Mod. You can import multiple sets at once if they are all copied to clipboard. As you can see in the image below, Ctrl + I is a shortcut.
Import from File: If you do not have anything copied to clipboard, trying to import with Auto-Legality Mod will ask you to select a file from your computer. This file should be a text file listing multiple consecutive sets. You can also trigger this by holding Shift while clicking Import with Auto-Legality Mod.
Import from URL: To generate Pokémon from a PokePaste or Pastebin URL, copy the URL to clipboard and use Tools > Auto-Legality Mod > Generate from URL instead.
Legalize Active Pokémon / Legalize Active Box / Legalize All BoxesLegalize Active Pokémon is more difficult to use than Importing Showdown Sets. It looks at the basic information entered for the active Pokémon in the left sidebar and then fills in extra information to make it legal. This option can be found via Tools > Auto-Legality Mod > Legalize Active Pokémon. The characteristics that must be legal before you start are the same as those for Importing Showdown Sets.
