 They change the deck again. Before this the Gaster card was not included in the official Undertale tarot. They only intended to publish about 18 cards in the deck and you could see all of them in sample, that's why the gaster card is removed in his wiki page in the first place.

 But now the card number is increased so there's a chance this card is in the deck.
