You should definitely add an "are you sure" prompt after choosing the pokemon to return to deck, it is extremely easy to select those you want to be shuffled instead, cos, you know, you can't misclick in real life. Of course, ideally, you shouldn't have removed the "undo" button like, two years ago or something, that was pointless.
Hello there nautiscarader,
Thanks for the suggestion!
This is definitely a good point for possible improvements.
I'm passing your suggestion to the developers for their review.
I've updated the title of your post and moved it to the correct area (Game Feedback) of the forums.
Hope this helps!
