Flicker of Fate
White has always had blink as a color pillar, but the target line is what widens this beyond a value spell: adding enchantments to the usual creature-flicker template turns it into a toolbox answer. At instant speed, the flexibility cuts several ways. On your own permanents it rescues a creature from targeted removal, re-triggers an enter-the-battlefield ability, or resets a token-maker; on an enchantment it re-fires a Saga from chapter one or replays an Aura that has done its work. Pointed at an opponent, it becomes a way to strip accumulated state that outright destruction cannot: the permanent leaves and returns, shedding any counters, attached Auras, and equipment, even though it lands right back on the battlefield. That reset-without-removal is the real wrinkle, and it is distinct from white's usual enchantment answers, which exile the permanent for good rather than launder it back onto the board. The exile-and-return also sidesteps regeneration and dodges destruction-based removal aimed at the same target, since the permanent is briefly not there to be destroyed. It asks nothing of graveyard or exile setup and demands no build-around; it simply wants a board with a reason to blink something, which any shell running enter-the-battlefield creatures or chapter-based enchantments naturally supplies.
