Letting you choose what to discard is very dangerous, they rarely let you do that and if they do it's expensive to. Luxray being a 2 prizer that only discards 1 and even that saw a little bit of play.
It's because it can become very easy to completely lock your opponent from playing. And that's 1 of the 2 things PTCI hates. 1 is locking your opponent from doing anything, 2 is donking the opponent before they get a chance to play. They're extremely strict on these types of concepts
