Those capsule things? Yeah, those were very pretty. Only thing I disliked is them making it mandatory for us to remove them before putting Pokemon into PC, which was sort of a hassle. =(
I got a few bred ones from Wonder Trade, but others were mainly throw-away--Pokemon you'd usually find yourself releasing if you have too much of it. Say, if you still those want those rare balls, have you tried looking around the forum if somebody's willing to give? Haha.
Yeah, I understand why some wouldn't want to be into competitive; in general, there are many things to be keeping up with, with more being added as new generations are introduced.
