Jund Wildfire grinds with recursive value from Ichor Wellspring, Refurbished Familiar, and Writhing Chrysalis, so Relic of Progenitus can exile cards from their graveyard to slow down any graveyard-based recursion, and its sacrifice ability exiling all graveyards can blunt Refurbished Familiar-style value if timed well (though note it doesn't stop madness or affinity, it does hit their card-draw loops that dump artifacts). Weather the Storm's lifegain helps us outlast their grindy, incremental damage plan. Malevolent Rumble and some Eldrazi Repurposers are trimmed since this matchup is more about card advantage attrition than early tempo, and we want more resilient answers to their engine.
