How would I make a script that saves an Instance? [closed]

I've been making a Pokemon game and I need it to save. There is a part called StoragePart in my game and in there is 2 folders, the 1st one is called YourPokemon where the Pokemon the player owns are stored and the 2nd one is called PokemonYouCanGet where the Pokemon that the player doesn't own and when a player catches a Pokemon, it duplicates the caught Pokemon and sends it to the YourPokemon folder and I need it to save. I've tried this script but it's not working:

DS=game:GetService("DataStoreService"):GetDataStore("Instances")
saved = {}
local Pokemon = game.Workspace.StoragePart.YourPokemon:GetChildren()
table.insert(saved, {
Pokemon[1].Name,
Pokemon[1].Level,
Pokemon[1].XP,
Pokemon[1].Nature,
Pokemon[1].NeededXP,
Pokemon[1].Image,
})
DS:SetAsync("Instances",saved)
