I just heard something terrible. Stay away from pokeballs! Sure, a cushy life with a trainer sounds good now, but I've checked some stores. Pre-cooked Tepig/Pignite/Emboar is a very common cheap meat nowadays. Sure, some trainers may not sell you out... but can you be sure that they're not just waiting for you to faint... then it's bye-bye pokeball, hello butcher.
