Skybind
Most blink effects point inward to re-trigger your own enters-the-battlefield value; this one aims the flicker outward and turns it into recurring interaction. Any enchantment entering the battlefield under your control (cast, reanimated, or arriving as a token) fires the trigger, exiling a nonenchantment permanent until the next end step: a blocker before combat, an untapped mana rock the turn the opponent most needs the mana, a planeswalker stripped of a loyalty activation. The return clause makes the exile temporary, so it functions as a tempo tax rather than removal. Where the deck can chain enchantments, though, the cadence compounds: two enchantments arriving on the same turn fire it twice, and a steady drip turns the board into a place where nothing the opponent controls is reliably available when it matters. The exile also resets the targeted permanent the ordinary way, so pointing it at one of your own creatures reuses an enters-the-battlefield effect when there is no better target. White rarely gets repeatable interaction with permanents it does not own, and here that interaction is laundered through the constellation subtheme rather than handed to the color directly: the design pays for the effect by gating it behind a commitment to enchantments as the engine. It is an engine piece first and a removal spell never, valued entirely by how many enchantment-entry events the rest of the deck can manufacture each turn.
