I don't have sufficient tournament data to answer this question. The matchup between Mono Black Eldrazi and Boros Energy shows 0 recorded matches in the last 60 days of Modern tournament data.
This could mean:
- These archetypes haven't faced each other in recorded tournaments during this period
- One or both archetypes may have very low meta presence
- The archetype names might not match exactly what's in the database
Would you like me to:
- Check the current meta presence of these archetypes?
- Look at their overall winrates separately?
- Try alternative archetype names (e.g., "Colorless Eldrazi" or "Energy" variants)?
