I should try to find the correct archetype name. Perhaps "Eldrazi Tron" is an alias for another archetype. Let me think about similar names. Maybe "Tron" is the main archetype, or "Eldrazi" as a separate one. But the user specifically mentioned "Eldrazi Tron," which might be a combination.
Since the get_archetype_overview failed, I need to check if there's an existing archetype that matches. Maybe the user meant "Tron" without "Eldrazi," or there's a different name. Alternatively, the database might not have data on Eldrazi Tron, especially if it's a newer deck.
Looking at the meta changes for Modern, there were several set releases and bans. The latest set released was Edge of Eternities in August 2025. Maybe Eldrazi Tron is a newer deck that hasn't been tracked yet. Or perhaps it's part of a different archetype.
Since the get_sources call returned zero tournaments, there's no data available for Eldrazi Tron in the specified period. The user might be referring to a deck that's not yet recognized in the database. In that case, the answer should state that there's no available data and suggest checking if the archetype name is correct or if it's a newer strategy.

The archetype "Eldrazi Tron" does not exist in the database, and no tournaments or data were found for this name in the Modern format between 2025-10-13 and 2025-12-12. This could indicate:
No winrate can be calculated due to insufficient data. Check the archetype name or consider broader searches for similar strategies.
