I always thought that the solution to the "lack of replayability" of the solo content is to have monthly quests. They would be complete a Dungeon Run, complete a Monster Hunt, complete a Rumble Run and complete an Arena run. They'd give you a pack or something equivalent. Being a monthly quest, it wouldn't be a big pressure to get it finished, but it's enough to keep playing the different formats.
It also fits in perfectly with the already existing "monthly quest" to get 5 wins on the ladder for your chest.

I added links from the tournament games for whoever want to take a look at how the deck does against competitive meta decks.

BGH is one of the only good Shadowflame target in this deck. This deck is heavy control and focus more on surviving so I guess he has is place in the deck.
