Settle Beyond Reality

The modality is the whole trick. Read the two lines separately and each looks like something white already had: exile a creature you don't control is a permanent-answering removal spell, and exile-then-return a creature you control is a flicker, the kind of blink white has been printing since Flickerwisp. Stapling them onto the same sorcery with "choose one or both" is what justifies the five-mana price, because the flicker half converts a piece of interaction into a value engine whenever your board has enter-the-battlefield triggers to reset. Point both modes at once and you strip their best threat while re-firing your own creature's arrival, all from one card. The exile clause on the removal half matters more than it reads: it sidesteps the indestructible bodies, death triggers, and graveyard recursion a destroy effect feeds, and it reaches tokens and recurring threats that white's board wipes cannot cleanly answer. The cost of all this flexibility is timing. This is a sorcery, so the flicker cannot be held up as a combat trick or a response to targeted removal; you commit on your own turn, at your own pace, which keeps a card this modal from doubling as a reactive blowout.
