Jund Wildfire's engine is entirely artifact-based (Ichor Wellspring, Fanatical Offering, Cleansing Wildfire's targets, Nihil Spellbomb), making Annul and Steel Sabotage premium disruption that can counter their card-draw artifacts before they generate value or bounce a Writhing Chrysalis-enabling Bridge. Deem Inferior and Sleep of the Dead are cut since this deck grinds with incremental value rather than presenting single big threats worth bouncing to the library. Keep Counterspell for their Refurbished Familiar and Writhing Chrysalis, and use Steel Sabotage to counter Ichor Wellspring on the stack before it enters the battlefield.
