Let me look up the Mono-Blue Goblin Charbelcher archetype first!
Hmm, that matched to Legacy Charbelcher. Let me search more broadly in Modern for this archetype.
Found it! The archetype is Mono Blue Belcher (a78aa6a1-f6ce-4387-8958-1c7da2f127ba). Now let me fetch the winrate over the last 60 days and the raw match data to compute a confidence interval.
No data in the last 60 days. Let me widen the window significantly to find any recorded matches.
Unfortunately, I don't have sufficient tournament data to answer this question. Here's what I found:
Mono Blue Belcher does exist as a registered Modern archetype in the database (color: U), but it has zero tournament entries and zero matches recorded at any point in the database — meaning it has never appeared in any tracked event.
This could mean:
"Blue Belcher" (WU / Azorius) and generic "Belcher" (colorless) do exist. Want me to check the winrate + confidence interval for one of those instead? Just say the word! 🧙
