I wanted to try and do sample hands against the opponent having hand traps, so I added cards to the Opponent's hand but then found out you cannot trigger or move them back to your side, they can only be targeted.
However, after adding a card to their hand and clicking Reset Deck, I get a Null Error when attempting to add the Max # of copies from Deck to Hand of the same card I just gave the Opponent.
You can see the glitch here and it's easily reproduced: https://www.duelingbook.com/replay?id=939014-75954627
