Sagu Wildling // Roost Seek 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
Flying When this creature enters, you gain 3 life. Search your library for a basic land card, reveal it, put it into your hand, then shuffle. (Also shuffle this card.)
Complete guide
Sagu Wildling // Roost Seek is a versatile green card that offers players a choice between a stabilizing flier and efficient library filtering. This card utilizes the Omen mechanic, allowing you to cast it as a sorcery that shuffles itself back into your library after resolving. Whether you need a mid-game threat or early-game mana fixing, this Dragon has you covered.
Understanding Omens
When you have this card in your hand, you choose how to cast it. You can cast Sagu Wildling as a 5-mana green creature with Flying, or you can cast Roost Seek as a 1-mana sorcery. Outside of the stack, the card is always a creature. However, if you cast Roost Seek, it functions entirely as a sorcery spell with its own mana cost and effect, ignoring the creature half until it leaves the stack.
The Resolution Process
If you cast Sagu Wildling, it enters the battlefield and its triggered ability goes on the stack to gain you 3 life. If you cast Roost Seek, you search your library for a basic land, reveal it, and put it into your hand. Crucially, as the sorcery resolves, the physical card is shuffled back into your library instead of being placed in the graveyard. This ensures you can potentially draw it again later as a creature.
Common Mistakes
The most important rule to remember is that an Omen only shuffles back into the library if it resolves successfully. If Roost Seek is countered by a spell or ability, it goes to the graveyard like any other spell. Additionally, while the card is in your graveyard or library, it is only a creature card named Sagu Wildling; effects that search for sorceries specifically cannot find it.
When to Play It
Roost Seek is an excellent turn-one play if you are missing land drops or need to thin your deck. Sagu Wildling is better suited for the mid-to-late game when you need to block flying threats or stabilize your life total against aggressive decks. Since the Omen version shuffles itself back, you don't lose the card's late-game value by using it for mana fixing early on.
Interaction examples
If you have Roaming Throne on the battlefield with 'Dragon' chosen as the creature type and Sagu Wildling enters the battlefield, the life-gain ability triggers twice. You will gain a total of 6 life because Roaming Throne sees the Dragon's triggered ability and adds an additional trigger to the stack.
If you need land on the battlefield immediately, Solemn Simulacrum is more efficient as it puts a land directly onto the battlefield. However, Roost Seek costs only one mana to find a land for your hand and returns itself to the deck. If you later draw and cast Sagu Wildling, you get a flying body and 3 life, whereas the Simulacrum provides a draw trigger only when it dies.

How it works : Sagu Wildling // Roost Seek
Original English text — Wizards of the Coast / Scryfall
- #1· Wizards of the Coast
As a player casts an omen card, the player chooses whether they cast the card normally or as an Omen.
No other card is named in this ruling.
- #2· Wizards of the Coast
An omen card is a creature card in every zone except the stack, as well as while on the stack if not cast as an Omen. Ignore its alternative characteristics in those cases. For example, while it’s in your graveyard, Twinmaw Stormbrood is a white creature card whose mana value is 6. It can’t be the target of the reflexive ability created by Kishla Trawlers’s triggered ability (“…When you do, return target instant or sorcery card from your graveyard to your hand.”).
No other card is named in this ruling.
- #3· Wizards of the Coast
When casting a spell as an Omen, use the alternative characteristics and ignore all of the card’s normal characteristics. The spell’s color, mana cost, mana value, and so on are determined by only those alternative characteristics. If the spell leaves the stack, it immediately resumes using its normal characteristics.
No other card is named in this ruling.
- #4· Wizards of the Coast
If you cast an omen card as an Omen, use only its alternative characteristics to determine whether it’s legal to cast that spell. For example, if you control Thundermane Dragon (“You may cast creature spells with power 4 or greater from the top of your library.”) and Twinmaw Stormbrood is on top of your library, you can cast Twinmaw Stormbrood, but not Charring Bite.
No other card is named in this ruling.
- #5· Wizards of the Coast
If a spell is cast as an Omen, its controller shuffles it into its owner’s library instead of putting it into its owner’s graveyard as it resolves.
No other card is named in this ruling.
- #6· Wizards of the Coast
If an Omen spell has one or more targets and all of those targets are illegal when the spell tries to resolve, it won’t resolve. None of its effects will happen, and it will be put into its owner’s graveyard. It won’t be shuffled into its owner’s library.
No other card is named in this ruling.
- #7· Wizards of the Coast
If an Omen spell is countered or an effect causes it to otherwise leave the stack, it won’t be shuffled into its owner’s library.
No other card is named in this ruling.
- #8· Wizards of the Coast
If an Omen spell is copied, that copy is also an Omen and is shuffled into its owner’s library as it resolves. Its owner still shuffles their library, but the copy ceases to exist as a state-based action.
No other card is named in this ruling.
- #9· Wizards of the Coast
If an effect instructs you to choose a card name, you may choose the alternative Omen name. Consider only the alternative characteristics to determine whether that is an appropriate name to choose.
No other card is named in this ruling.
- #10· Wizards of the Coast
Casting a card as an Omen isn’t casting it for an alternative cost. Effects that allow you to cast a spell for an alternative cost or without paying its mana cost may allow you to apply those to the Omen.
No other card is named in this ruling.
