This is a SAV file that is the best for competetive battling.It has most of the movesets for all of the Uber pokemon (Best pokemon).All of the pokemon are legit. (Allowed to be used in tornaments/ not fake/ not made using cheats)
Or when your player dies, you can say in code, if enemy exists, do nothing, but if enemy does not exist, then create enemy at certain spot. (This would be a pain tho for lots of emeies)
