I can’t add prince Renathal to my death knight wild deck

I can find him in all my wild decks but the death knight, when i am building the death knight deck even when i search i wont find him.

What happens if you filter just for the castle Nathria expansion ?
Then what if you enter the crafting menu and check all owned and missing boxes ?

Renathal has been granted for free for every one for alimited time last expansion. In case you never got the regular one, all you need is to buy a Castle Nathria pack and go to the pack opening screen, you’ll get him before opening your pack.

Are you sure that deck is wild?

It worked thank you all
