Jund Wildfire grinds with sacrifice synergies (Gixian Infiltrator, Writhing Chrysalis) and recursive card draw from Cleansing Wildfire, Ichor Wellspring, and Fanatical Offering. Extract a Confession is strong here, forcing them to sacrifice their biggest threat, which can strip a growing Gixian Infiltrator or Writhing Chrysalis. Cast Down and Toxin Analysis are fine but slightly less impactful than proactively stripping their board, so we trim one of each for the sacrifice effect.
