The next Hearthstone Mini-Set arrival is a mystery, or isn’t it? Today we solve when the Murder at Castle Nathria miniset comes.

Today, in full Murloc Holmes fashion, I am here to tell you why the Hearthstone Mini-Set for Murder at Castle Nathria expansion should come next week. This is not just guessing, I go by the facts, and those indicate that we might be getting a Hearthstone announcement for the Mini-Set as soon as tomorrow. Join me while we unravel this mystery.

UPDATE: I was right! Hearthstone announced the Maw and Disorder Miniset coming on September 27th, check out the new cards and mechanichs.

What is a Hearthstone Mini-Set?

Hearthstone introduced Mini-Set in January 2021 with the Darkmoon Races Mini-Set for Madness at the Darkmoon Faire expansion. These Mini-Set bring new and exciting content for Hearthstone players in the form of 35 extra cards.

Usually, the cards included in this Hearthstone Mini-Set are divided the following way:

  • 4 Legendary cards
  • 1 Epic card
  • 14 Rare cards
  • 16 Common cards

Remember that Epic, Rare and Common cards come in pairs. So 35 unique cards in each Mini-Set.

Murder at Castle Nathria Mini-Set announcement and arrival

As mentioned above, every clue indicates that the Murder at Castle Nathria Hearthstone Mini-Set will come next week. Why do I feel so confident with this hypothesis? These are the facts. You will see it's all about connecting the dots!

1. Heroic Brawliseum

Players say Blizzard is a greedy corporation that is only concerned with emptying your pockets. Well, let's just agree that they like making money. Here we find our first clue, with the Heroic Brawliseum currently running.

This 1000 Gold per ticket event, kind of drains gold from players. Gold that players could use to buy the upcoming miniset. Before you say this is just my imagination, do you remember when was the last time we had a Heroic Brawliseum? You guessed it, the week before Hearthstone announced the Sunken City expansion Mini-Set. A coincidence?

2. Hearthstone Esports Events

So, what? You may say, a Heroic Brawliseum isn't proof of anything. Well, hold on there while I present you the second fact, the upcoming Hearthstone Masters Tour. Why is Hearthstone esports relevant? Because it's a marketing tool. Abar, Hearthstone Esports Product Manager, explained that so many times already.

What this means is that, with the next Masters Tour starting on October 7th, is just natural to expect some new content before that. Given a 10-day window for players to adjust and refine their line-ups and what do we get? That the next Hearthstone Mini-Set should arrive on September 27th.

3. Hearthstone Mini-Set timings

Not convinced yet, well, coming up next, the most revealing of all the facts presented. Hearthstone patch cycles are no mystery, and while they aren't a perfect clock, they are reliable. Minisets come with the X.4 Hearthstone patches, which go live approximately 2 months after the expansion launch.

This is not just me saying it. Iksar, former Hearthstone Game Director, was the one who gave this guideline I take to predict the miniset. But just to be sure, here are the dates for the 5 previous mini-sets.

Expansion Name
Release Date
Release Date
Sunken City
Throne of the Tides
Divided in Alterac Valley
Onyxia's Lair
United in Stormwind
Forged in the Barrens
Wailing Caverns
Madnes at the Darkmoon Faire
Darkmoon Races
Expansions and Mini-Set cycles

Out of the 5 minisets Hearthstone released, only one didn't follow the 2-month rule, the Deadmines Mini-Set for United in Stormwind, but there is an explanation for this. In October 2021, Blizzard released Mercenaries, a new Hearthstone game mode, which pushed the miniset to November that year.

Do you still think this is just a coincidence? Time will prove me right or wrong, but I stick to my gut, and my gut tells me that Hearthstone should be announcing the Murder at Castle Nathria expansion Mini-Set this week. Furthermore, that said Mini-Set should be going live in less than 10 days from now.

If you think this is just me being full conspiracy theorist, stay tuned to for more Hearthstone news and updates to prove me wrong. See you next time, in the Tavern.
