Hi there,
In case anyone wants to revisit some old adventures or hadn’t got the card back back in the day — and I’ve found out that such players are not at all alone in the internet — you might find out that the AI has since been tuned and old solutions no longer work for some bosses. The encounter in question has turned out to be quite notorious in that regard, judging by my previous web searches, and I’ve had that one unfinished for some time (about one year and a little, having returned to Hearthstone after abandoning it shortly after Un’Goro’s launch). However, now I present a possible solution using only old cards and newer core/cheap cards that can beat the encounter. Essentially, this is an old N’Zoth paladin, the workings of which were quite well-known back in the day, with Renathal and a lot of cards for healing and stalling. Below is a sample decklist (I’ve actually had to recreate it, since I’d deleted the deck first after beating the encounter, but then decided to share in case it is still useful for someone looking for a modern solution), but you can, of course, substitute some cards and experiment, depending on your collection (I wasn’t actually that thorough when building the deck, so there might be even better alternatives). I was finally able to do it on my second attempt (and finally get that card back).
PS Anyfin paladin might work again with Renathal, but I’ve not tested it.
