>>24532051>but avoids the ridiculous stuff like being able to start with a Legendary and seeing fully evolved mons at the beginning of the game?Pretty much every randomizer has that as a setting. You can make it so Legendaries never appear in the wild (though you can shuffle the Legendaries that appear in special places with each other sometimes), you can make it so you get the first stage of a three-stage line for your starter, etc. Pic related, check out the Universal Pokémon Randomizer.
