Misfortune's Gain

Unconditional creature destruction in white has always come with a tax, and here the tax is paid to the opponent: four life handed back to whoever owned the creature you just killed. That is the lever white removal has historically leaned on. Swords to Plowshares exiles but gains the controller life; Path to Exile fixes a land; Condemn shuffles a creature away while padding its owner's total. This one pays full price by destroying any creature outright, no toughness cap, no creature-type restriction, and then settles the bill with a life rebate rather than an exile clause or a card disadvantage. The trade matters more when you are the aggressor than when you are defending: against a slow opponent you are trying to pressure, four life back to them is a real concession, while against an aggressive board the life is close to irrelevant and you have simply traded four mana for their best threat. The sorcery speed is the other half of the cost, ruling it out as a combat trick or an end-of-turn answer and forcing you to spend a main phase on it. Compared to white's cheaper exilers, the four-mana rate is plainly behind the curve, which places this firmly in the category of redundancy rather than premium removal: a kill spell you reach for when you have run out of the better ones, valued for hitting anything and asking only that you accept giving a little life away.
