Missing a card from the free welcome back deck (paladin)

I chose paladin and now to get the last card “Lokholar the Ice Lord” I’m supposed to win a game at 15 hp? Isn’t the point of these decks to let you get back in the game right away?

Not sure I understand - is this card supposed to be a part of the welcome back deck?

If yes, maybe, you need to contact support?
