Now I'll search for Neoform decks across relevant formats. Since Neoform is a Modern-legal card (GU sorcery), I'll query for decks playing it in Modern over the last 60 days and analyze the color combinations.
This is interesting - I only found one entry. Let me search more broadly to see if Neoform is played in other formats or if there are archetype names I should look for:
Great! Now I can see Neoform is primarily played in Modern (Neobrand archetype). Let me analyze the color combinations for the main Neoform decks:
Let me broaden the date range to get more data from the full year of Neoform/Neobrand:
Let me look at the archetype color directly from the archetypes table and sample some recent Neobrand decks to see their actual composition:
Perfect! Now let me check the archetype color from the database and also look at some recent variants to compare performance:
Excellent! Now let me get sources to cite:
Perfect! Now I have all the data I need. Let me provide a comprehensive answer about Neoform colors based on the tournament data.
Based on Modern tournament data from 2025, the overwhelming best color combination for Neoform is straight Simic (Blue-Green), which accounts for 465 of 496 Neoform entries this year with a solid 52.2% winrate. The classic Neobrand archetype operates efficiently in just two colors, using Neoform alongside Eldritch Evolution, Allosaurus Rider, and Summoner's Pact to quickly assemble game-winning creatures like Ghalta, Stampede Tyrant and Griselbrand.
The only meaningful alternative is Bant (White-Blue-Green), appearing in 16 Simic Ritual entries with an impressive 57.7% winrate. This splash adds white for additional interaction or payoffs. All other color combinations - including Sultai variants adding black - had minimal representation with fewer than 5 entries each and generally worse performance.
The data is clear: if you're playing Neoform in Modern, stick to Simic. The manabase consistency and focused gameplan outperform greedier color combinations.
