2 matches in a row I played and use this card - the “duel” card was passed back and forth between myself and my opponent, and both times the damage to be dealt was in the high 20s/low 30s - then suddenly it disappeared from my opponents hands and did NOT detonate. It did not swing back to me either, it just vanished.
Plenty of ways this might have happened.
Your hand was full when your opponent tried to send the Pick back to you.
Your opponent’s hand was full when you tried to send the Pick back to him.
You played some card that shuffled the Pick back into your deck.
Your opponent played some card that shuffled the Pick back into his deck.
Etc etc etc.
Without a game replay recording, there’s no practical way to investigate further.
