This devious combination turns your own library-reshuffling spell into a game-ending weapon by weaponizing Hive Mind to force your opponents into casting copies of Paradigm Shift. While Hive Mind ensures the contagion spreads to the rest of the table, Lithoform Engine steps in to multiply the madness by copying the trigger itself, ensuring that every single rival gets hit with multiple copies of the spell. As those copies resolve and exile your opponents' libraries, your original Paradigm Shift safely resolves last, resetting your own graveyard and leaving you as the sole survivor in formats like commander, legacy, oathbreaker, and vintage.
