Wander Off

Black paying four mana to exile a creature is the tell here: this is a color deliberately borrowing an effect that belongs to white and paying a tax for the privilege. Black's removal has always leaned on the caveat. Doom Blade won't touch black creatures; Ultimate Price cares about a single color; edict effects like Diabolic Edict let the opponent choose the sacrifice; and destruction, black's native verb, folds to indestructible and regeneration and death-trigger payoffs. Exile sidesteps every one of those escape hatches, which is precisely why it has historically sat outside black's slice of the color pie. What makes the design coherent is the rate. At instant speed with no conditions on the target, the answer is airtight; the four-mana price is what pays for a universal, no-strings exile in the color that most wants clean removal without turning it oppressive. The result is a spell that swaps black's usual efficiency for a fix to black's usual weakness (the difficulty of permanently answering a resilient threat), and lands somewhere black rarely gets to stand: an unconditional removal spell with no fine print at all.
