Omen of the Sea card art
Omen of the Sea earns its slot by letting you scry 2 and draw a card the moment it resolves, then offering a second scry 2 on demand when you sacrifice it later — two meaningful card-quality events from a single two-mana enchantment. The cost is real: two mana for a draw-one is below rate on raw efficiency, which is exactly why Yorion, Sky Nomad decks prize it so highly, since blinking it resets the enter-the-battlefield trigger and turns one card into a repeatable filtering engine.

Commanders with the highest synergy

01
Yorion, Sky Nomad

Yorion, Sky Nomad

56.1% of decks · synergy 0.52

Yorion, Sky Nomad appears in over 56% of decks running Omen of the Sea for an obvious reason: blinking the enchantment re-triggers the scry-2-draw-1 every time Yorion connects, converting a modest cantrip into a card-advantage loop that compounds across a long game.

02
Brago, King Eternal

Brago, King Eternal

42.4% of decks · synergy 0.38

Brago, King Eternal does the same blink math as Yorion but cheaper — every combat phase where Brago deals combat damage to a player resets Omen of the Sea's ETB, stacking scry and draw triggers alongside every other permanent in the deck.

03
Abdel Adrian, Gorion's WardCandlekeep Sage

Abdel Adrian, Gorion's Ward // Candlekeep Sage

41.3% of decks · synergy 0.37

Abdel Adrian, Gorion's Ward // Candlekeep Sage generates a stream of blink effects as a core game plan, and Omen of the Sea slots in as a low-cost enchantment that pays off each time Adrian's ability fires rather than sitting as a static piece.

04
Kenessos, Priest of Thassa

Kenessos, Priest of Thassa

22.5% of decks · synergy 0.21

Kenessos, Priest of Thassa wants the top of the library to be a Kraken, Leviathan, Octopus, or Serpent before activating, and Omen of the Sea's enter-the-battlefield scry 2 — plus its sacrifice scry 2 — gives Kenessos reliable, repeatable control over exactly what sits on top.

05
Galadriel of Lothlórien

Galadriel of Lothlórien

19.6% of decks · synergy 0.19

Galadriel of Lothlórien rewards scrying by putting cards directly into play, so Omen of the Sea's double scry triggers translate into concrete permanents rather than just deck manipulation — the sacrifice mode in particular lets you scry at instant speed to set up Galadriel's trigger on an opponent's turn.

Format Analysis

Where it lives, where it can’t

FormatVerdict
commander
legacy
modern
pioneer
standard
vintage
pauper
oathbreaker

In Commander, Omen of the Sea is a reliable role-player rather than a staple — blink commanders treat it as an engine piece, and scry-matters decks like Kenessos use it as cheap setup, but the rest of the field views it as a budget cantrip that competes with stronger options. In Pauper, where card-quality spells at common are genuinely scarce, Omen of the Sea is more competitive: instant-speed sacrifice lets it operate as a combat trick or end-step filter, and the two discrete scry events matter in a slower format built around incremental advantage. Legacy, Vintage, and Modern have access to so many efficient draw and filter spells that Omen of the Sea doesn't see meaningful play there — it isn't doing anything those formats can't do faster or for less investment. Pioneer sits in between: the card is legal and the ceiling is real in enchantment-blink shells, but dedicated constructed decks have largely moved past it.

$0.37 bulk tier

At $0.37, Omen of the Sea is deep bulk — you'll find it in any common box or pick it up as throw-in without thinking twice. Bulk enchantments with narrow but genuine synergy tend to stay at this price floor indefinitely, so there's no urgency and no upside to holding copies for value.
