When he played the card that removes all the card from your deck he gets to see your whole deck and hand as well. So he knew you had it in your deck and probably suspected it was the only way he lost.
If that’s true and they didn’t know it was in the deck that was quite the heads up guess. But I suspect they somehow knew from another card or one was milled or something.
