Omen of the Sea

Scry 2 then draw a card at instant speed is one of the oldest smoothing effects in blue, printed many times over as a sorcery or an instant that resolves and vanishes. The Omen cycle's whole intervention was to attach that effect to a permanent, so the card the flash mode leaves behind counts toward devotion, answers to enchantment tutors, and lingers as fuel for enchantment-matters payoffs. The entering trigger front-loads selection: you scry 2 first, arranging the top of your library, then draw a card off that setup. The other decision the card poses comes later, once the enchantment is sitting on the board doing nothing: pay three mana to sacrifice it for another scry 2. That second mode is pure selection, not more cards, and it doubles as a way to clear the permanent off the table when its lingering presence stops earning its keep. Flash is what makes the front half a tempo play rather than a tapped-out main-phase commitment: hold up two mana, react to the opponent, and refill on their end step. Nothing here is fast or individually powerful; the reason to run this over the many roughly equivalent draw spells is that a smoothing effect which also leaves a permanent behind is worth more to certain decks than the same effect that evaporates on resolution. It is a template answer to a narrow question: what kinds of card selection can be built to matter twice?
