I'll analyze the winrate difference between Modern Broodscale decks with and without Writhing Chrysalis. Let me start by getting the relevant IDs and then query the data.
Now let me query the database to compare winrates between Broodscale decks with and without Writhing Chrysalis. I'll use the last 60 days for a good sample size.
Now let me get some sources to back up this analysis:
Based on my analysis of Modern Broodscale decks over the last 60 days (July 19 - September 17, 2025):
Without Writhing Chrysalis:
With Writhing Chrysalis:
The data shows that Broodscale decks perform better without Writhing Chrysalis by 4.2 percentage points (51.5% vs 47.3%). This difference is based on nearly identical sample sizes (67 vs 68 entries) and represents a meaningful performance gap.
The slightly higher draw rate in Chrysalis builds (7.3% vs 4.9%) suggests these games may go longer, but this doesn't translate to better match wins.
This suggests that while Writhing Chrysalis provides additional utility and synergy with the Eldrazi sacrifice theme, the more streamlined builds without it may be more consistent or efficient in the current Modern metagame.
