Sever the Bloodline

Exile, not destruction, is the first thing this removal spell buys, and the second clause is the reason it earns the rate: by sweeping every creature sharing the target's name, it answers token swarms and the recurring legend in a single cast. Against a board of identically-named tokens, one cast clears all of them; against a problem creature that keeps coming back from the graveyard or a second copy already on the battlefield, exile leaves nothing to recur and the name-match catches the duplicate. That makes it a removal spell that scales with how concentrated the opposing board is: it does nothing extra against a wide spread of distinct creatures, but punishes decks built on redundancy. Flashback is the structural counterweight, its heavy graveyard cost turning a single card into two answers across a long game, banking value rather than spending it all up front. The pairing of a clean exile mode with a graveyard recast is the design logic of removal built to outlast attrition, trading raw speed for staying power. The sorcery timing is the price of that durability, denying the instant-speed blowout and forcing the cast onto your own turn. For a black deck grinding the long game, few four-mana answers ask for less and return as much over the full arc of a match.
