I'll check tournaments after September 15, 2025 to see if there are any that look like Premodern tournaments with lots of unknown/conflict archetypes.
Let me check what tournaments exist after September 15, 2025 first:
Now let me check the archetype distribution in these tournaments to see which ones have unusually high rates of "Unknown" or "Conflict" entries:
Let me also check if there are any tournaments with unusual format names or sources that might indicate Premodern events:
Based on my analysis of tournaments after September 15, 2025, I do not see any that look like Premodern tournaments. Here's what I found:
All 30 tournaments from September 15-21, 2025 show 0% "Unknown" or "Conflict" archetype entries. Every entry has been successfully classified into a known archetype. The tournaments are exclusively standard MTG formats: Legacy, Modern, Pauper, Pioneer, Standard, and Vintage, all from established sources (MTGO and Melee).
The complete absence of "Unknown" or "Conflict" entries across all tournaments suggests these are well-established formats with mature archetype classification systems, not experimental or unsupported formats like Premodern that might have many unclassified decks.
If Premodern tournaments were present in the data, I would expect to see high percentages of "Unknown" entries due to the format's diverse, often unique deck compositions that don't fit into standard archetype categories. The clean archetype classification across all recent tournaments indicates these are mainstream competitive Magic formats only.
Sources: Data from 30 tournaments: 87% MTGO, 13% Melee.
Let me check if there are any Unknown archetype entries in Modern after September 15th:
Now let me look at the cards in this single Unknown entry:
Let me check what's happening with this Unknown entry - it exists but has no cards recorded:
Let me check if there are any deck cards for this specific entry:
Let me expand the search to look at all Unknown archetype entries in Modern over a longer period to find patterns:
Now I can see a clear trend! Let me get more details about how many total Unknown entries we're looking at:
Based on my analysis of the Unknown archetype entries in Modern, I've found a clear trend. Looking at 21 Unknown entries across 16 tournaments since August 1st, these appear to be Domain Zoo or 5-color aggressive decks that the archetype classification system is struggling to categorize.
The card pattern is unmistakable: heavy manabase with all 5 colors (Sacred Foundry, Temple Garden, Steam Vents, Stomping Ground, Blood Crypt, Overgrown Tomb, Hallowed Fountain), premium fetch lands (Wooded Foothills, Arid Mesa, Windswept Heath, Flooded Strand), and key Domain payoffs like Leyline of the Guildpact (4 copies average) and Leyline Binding (4 copies average). The presence of new Duskmourn cards like Elegant Parlor and Lush Portico suggests these are updated Domain builds.
The classification difficulty likely stems from the archetype's hybrid nature - it combines elements of aggro (Bloodbraid Marauder), combo (Electrodominance, Living End package), and midrange strategies. Cards like Malevolent Rumble, Incubation//Incongruity, and Manamorphose at 4-copy densities suggest these are refined builds, not random brews.
Interestingly, one of these "Unknown" decks just won a tournament on September 21st (5-1-1 record), indicating these aren't failed experiments but potentially underrecognized viable strategies that need better archetype classification.
Sources: Data from 10 tournaments: 20% Melee, 80% MTGO.
