Sigiled Starfish is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

Official card text

: Scry 1. (Look at the top card of your library. You may put that card on the bottom.)

Complete guide

Sigiled Starfish, affectionately known as the 'Scryfish' by the community, is a reliable blue utility creature that provides consistent card selection. Its simple yet effective tapping ability allows you to filter through your deck every turn, ensuring you find the answers you need.

Understanding Scry 1

The core of Sigiled Starfish is its activated ability. By tapping the creature, you perform the Scry 1 action. This involves looking at the top card of your library. You then have a binary choice: leave the card on top if it is useful, or put it on the bottom of your library if it is not. This does not count as drawing a card, so it will not trigger effects that care about card draws.

Step-by-Step Resolution

First, ensure Sigiled Starfish does not have summoning sickness; it must have been under your control since the beginning of your most recent turn. Second, pay the cost by tapping the creature. The ability goes on the stack. Once it resolves, you look at the top card of your library. Finally, you decide its placement. Because this is an activated ability, you can use it during your opponent's end step to set up your next draw.

Common Pitfalls

A common mistake is forgetting that Scry happens before you draw. If you want to affect your normal draw for the turn, you must activate Sigiled Starfish during your upkeep or earlier. Additionally, if an effect requires you to shuffle your library after a Scry, the card you put on the bottom (or kept on top) will be lost in the shuffle.

Strategic Timing

Sigiled Starfish is best utilized as a defensive blocker that generates value. Since it has 3 toughness, it can survive early combat against small attackers. You should generally wait to activate its ability until the last possible moment—usually the opponent's end step—to keep the creature available for blocking if necessary.

Interaction examples

Early Game Setup

Ornithopter of Paradise

On turn two, you cast Sigiled Starfish. On turn three, you cast Ornithopter of Paradise using your lands. During your opponent's turn, you tap Sigiled Starfish to Scry 1. If you see a high-cost spell you cannot cast yet, you put it on the bottom, hoping to draw a land next turn to utilize the mana from Ornithopter of Paradise.

Optimizing Artifact Costs

Foundry Inspector

With Foundry Inspector on the battlefield, your artifact spells cost less. You can use Sigiled Starfish during your upkeep to Scry 1. If you see an artifact card, you keep it on top. You then proceed to your draw step, draw that artifact, and cast it for a reduced cost thanks to the Inspector's passive ability.
