Let me look that up for you!
The data I have for Broodscale Combo is in Pauper, not Modern. The archetype has a recent overall winrate of 53.6% in Pauper across 596 tournament entries. However, the last 60-day window shows no recorded matches, which suggests the data is from further back or the archetype has dropped off recently in tracked events.
If you were asking specifically about Modern, I don't have a Broodscale Combo archetype on record for that format. It's possible the deck is being tracked under a different name there. Could you clarify the format you're asking about, or share any alternate names it might go by?
Sources: Data pulled from the Pauper archetype database (596 entries historically). No matches found in the last 60 days for this archetype. Use get_sources() for specific tournament links once an active window is confirmed.
