Hearthstone trail blazed the way for the Rogue Like Deck Builder genre when they released Dungeon Run, even beating Slay the Spire (largely credited with popularizing the genre) to market. You guys made some great follow up modes that I still play to this day. But its been a long time since Tombs of Terror, and the stuff since then has been minimal and not all that replayable.
Now the roguelike deckbuilder genre is booming, Ballatro, Monster Train 2, Vampire Crawlers, Slay the Spire 2, it would be great to see what modern Hearthstone can do in the space. Can we get some new replayable single player content?
