Jund Wildfire's entire plan revolves around artifacts like Ichor Wellspring and their Bridge lands, so Dust to Dust exiling two artifacts at once is devastating value against their sacrifice-and-draw engine — note that exile gets around the Bridges' indestructibility since Dust to Dust doesn't destroy. Prioritize exiling Ichor Wellspring before it triggers again or hitting a Bridge land to disrupt their fixing. Cut a couple of the less impactful removal spells like Grim Bauble (whose -2/-2 won't reliably kill their bigger threats like Writhing Chrysalis) and some copies of Thraben Charm to make room, since Dust to Dust attacks their core gameplan more directly than incremental removal.
