I'll analyze Tron's performance with and without Sowing Mycospawn over the past 4 months in Modern. Let me gather the necessary data.
Now I'll query the database to compare Tron's winrate with and without Sowing Mycospawn over the past 4 months (May 6, 2025 to September 6, 2025).
Let me also get some tournament sources to provide citation for this analysis.
Based on the tournament data from the past 4 months (May 6 - September 6, 2025), Tron was significantly better WITH Sowing Mycospawn.
Tron WITHOUT Sowing Mycospawn:
Tron WITH Sowing Mycospawn:
The data shows a 5.0 percentage point improvement in winrate for Tron builds running Sowing Mycospawn in the maindeck. This represents a meaningful performance difference, suggesting that the card's ramp effect and versatility (with the kicker for land removal) provides substantial value to the archetype.
Interestingly, while Mycospawn builds are still the minority (40.5% adoption), they consistently outperform traditional builds across this 4-month sample.
