• The Backup Singers are a reference to the Hearthstone adventure One Night in Karazhan.
• The Medivas were originally introduced as a trio of characters featured in the promotional material for One Night in Karazhan before later making in-game appearances in the HS Party Portals! HS Tavern Brawl. Most of the Backup Singers' quotes are references to lines spoken by the Medivas in Party Portals!.
• HS Firelands Portal, widely considered one of the more powerful cards from the adventure, is a mage spell which deals damage to a target enemy and summons a random 5-Cost minion for the player.
• HS Purify is a priest spell which has the effect of Silencing a friendly minion and drawing a card. The card was widely mocked by Hearthstone players for being one of the worst cards in the game and for being released for a class that was already considered weak at the time.
