Blessed Light

Five mana to exile a creature or enchantment at instant speed is a rate almost nobody would build a competitive deck around, and that is the design brief, not a failure of it. This is catch-all removal aimed at the layer of the game where the relevant question is not "how cheap" but "can I answer the thing that just resolved." Exile sidesteps regeneration, indestructibility, and death triggers; the enchantment clause covers the auras, anthems, and lock permanents that white's cheaper spot removal often cannot touch. The breadth of the two target types is the reason it costs what it does. An instant that handles both halves of white's most common problems carries a tax any tuned removal suite would refuse to pay, so the price buys reach rather than efficiency. It sits in white's long tradition of "answer anything, eventually" instants: deliberately overcosted, deliberately wide, built so the floor is never "I have no out." The color that has the cleanest exile-based removal, from Swords to Plowshares through Path to Exile, has also always kept a slower, broader option on the shelf for decks that value coverage over speed. This is that option pushed to its widest single-target form. That is a real design job, just not a competitive one.
