Other mistake: When Dr Collector activates Graceful Charity for the second time, he has it in his right hand. He then appears to lower the card off-screen, but then he goes to draw three cards from his deck with his right hand. He never placed Graceful Charity on his duel disk or sent it to his graveyard. It's just never seen in his hand again. (00:12:24)
