As of now, there is no official announcement from Blizzard Entertainment regarding a "Day of Rebirth Mini-Set" in Hearthstone that adds 38 new cards. The name "Day of Rebirth" does not match any known expansion or mini-set in Hearthstone's official release history. Hearthstone has released numerous expansions and mini-sets over the years, such as: The Boomsday Project (2017) Rise of Shadows (2018) Mean Streets of Gadgetzan (2016) Galakrond's Awakening (2020) Dawn of the Mad Mage (2021) The game typically releases new content in themed sets, often tied to major story arcs or anniversaries. A 38-card mini-set would be unusually large for a standard mini-set (which usually includes 15–30 cards), so it's possible this information is speculative, fan-made, or based on misinformation. If you're referring to a recent rumor or an in-game event, it’s best to check official sources like the Hearthstone website, the official Hearthstone Twitter/X account (@PlayHearthstone), or the in-game news feed for accurate updates. Let me know if you'd like details about a specific expansion or set!

Here's a polished and engaging summary of Hearthstone’s Day of Rebirth Mini-Set release, ideal for use in a news article, blog post, or social media announcement:
