For some archetypes, nothing changed. Overall, the meta looks similar, but if you take a closer look... (As usual Gumeta.web.app was used as main source of informations :)
War is still in first place in terms of popularity. Zoo War remains balanced. In good hands, it can achieve a much better win rate than the average 50%. This archetype, even with poor piloting skills, rarely falls below a 50% win rate due to the deck's inherent nature.
Carvings, however, has shown quite terrible stats today. This deck is the opposite of the Zoo archetype: it requires good piloting skills, a fully optimized deck, and a bit of luck. Without these, it struggles to even maintain a 50% win rate.
Ok, Amazons are the new Zoo War. I think the Sanctum changes hurt War the most, and Amazons are now taking the top spot for aggro decks. It's an all-in deck, but most meta decks cannot fully avoid the face damage. Amazons, with additional support cards from ToD, can easily chip away at a few HP even without controlling the board.
Mutations are becoming quite popular. However, this is a deck where players can make several mistakes every turn, leading to a super low win rate overall.
Atlanteans don’t care about any meta shifts. It's a strong, solid deck, and only a core rebalance could harm its performance.
With no more Void hate and three sleep counterspells removed in the new Sanctum, I expected a huge shift for Death. However, I don’t see much change happening here—at least not yet. Maybe it’s too early to tell.
No changes in four weeks, really. Aggro is still strong, and Mayday is okay. But remember, GP balance changes are incoming! Maybe it will result in a buff for some Deception archetypes.
Zoo Light is solid and stable. A huge advantage of this archetype is that most Light cards can also be used in formats like Genesis. This makes shiny decks an excellent ROI.
I hope you enjoyed the reading!
