Bank Ball Collector
Thanks so much for your replyYes Heavy Ball Beldum caught in SM wasn't legal because of a glitch in the capture mechanics of the Heavy Ball where Pokémon weighing 220.2 lbs or under with a capture rate 20 or under cannot be caught because their capture rate is 0, which was the minimum cap for capture rates in SM. Beldum weighs 209.9 lbs so it fits in the category of weighting 220.2 lbs or under and has a capture rate of 3 so it is therefore one of the Pokémon that cannot be caught in a Heavy Ball in SM. It was fixed in USUM by capping capture rate at a minimum of 1, which allo such Pokémon to at least have a chance to be caught. The only other post Gen 3 games the Heavy Ball was available in were HGSS and because Beldum is only obtainable as a Safari Pokémon and a gift Pokémon, it can only be in a Poké Ball that is an ordinary Poké Ball and a Safari Ball.
