Mirage takes from the opponent’s hand. I assume the one you were replying to was talking about specific cards that add to the opponent’s hand. Usually cards with this effect will have a specific list of cards that it will pull from. But that could change, cards are added every day.
Out of curiosity, are the cards that are generated pulled off a list of cards outside a person’s deck or pulled from the person’s deck?

I’m talking about the cards that generate cards. edit: spacing
