Gild
Unconditional creature exile usually carries a tax somewhere: a higher price, a delay clause, a downgrade that keeps it honest. This one prices the answer in the most literal way possible, by handing back a Gold token, a one-shot mana rock that sacrifices for any color. But the token goes to you, the caster, not to whoever owned the exiled creature. That is the detail that flips the spell's intent. Compensation aimed at your opponent would make this a slightly apologetic removal spell; compensation aimed at yourself makes it a removal-shaped enabler that can point inward. Exile an enemy threat and ramp off the kill. Or exile your own creature: a token about to die, a body you are about to lose to a sweeper, anything you would rather convert to fixing and a fast mana than leave on a board you no longer want it on. The line is yours to read, and the colorless-flexible mana means the spell quietly doubles as fixing when a turn demands it. As clean creature removal it is honest if unspectacular. As a spell that can target your own side to ritual out tempo while clearing a liability, it carries more design intent than the rate suggests: the rare answer where the value it leaves behind is always yours, whichever direction you aim it.
