Prayer of Binding

White has always paid a premium for the privilege of answering anything: the color's clean unconditional removal tends to arrive stapled to a body or a caveat, and its permanent-exile effects historically wore the Oblivion Ring template, a sorcery-speed enchantment that trades away for value the moment it dies. This tightens that lineage in two ways. The flash keyword turns a reactive sorcery into an instant-speed interaction window, so it can ambush a permanent on the stack's terms rather than only on your main phase, and the target restriction (a nonland permanent an opponent controls) fences off the classic Oblivion Ring self-blink loop that let older versions reset their own enters-the-battlefield triggers. What you lose in flexibility you get back in tempo and coverage: creatures, planeswalkers, artifacts, enchantments, even a threatening battle-adjacent permanent all fall under one answer, held up on the opponent's turn. The gained life is the smallest part of the card and the most telling, a two-point cushion that quietly buys back a turn against the aggressive decks this most wants to stop. It is temporary removal, and the permanent returns when the enchantment leaves, but flash-speed universal exile with a life buffer is a genuinely different tool than the durdle-and-hope O-Ring it descends from.
