Arcanist's OwlHow it works & interactions with other cards

What It Does

Arcanist's Owl is a 3/3 flyer for four mana that can be cast using any combination of White or Blue mana. Its primary utility comes from its enters-the-battlefield ability, which allows you to look at the top four cards of your library and pick either an artifact or an enchantment card to add to your hand. This helps find key combo pieces or resilient threats while placing the unused cards safely at the bottom of your deck.

Step-by-Step Resolution

When Arcanist's Owl enters the battlefield, its triggered ability goes on the stack. First, you look at the top four cards of your library. From those four cards, you may choose one card that has the 'Artifact' or 'Enchantment' type. If you choose one, you must reveal it to all players before putting it into your hand. Finally, you take all remaining cards from those four and put them on the bottom of your library in a random order.

Common Mistakes

One common mistake is forgetting that you must reveal the card if you choose to take it; this is required so your opponents can verify it is a legal choice. Additionally, keep in mind that the cards not chosen go to the bottom in a random order, not an order of your choice. Finally, remember that while you can choose an Artifact Creature or an Enchantment Creature, you cannot choose a non-artifact, non-enchantment card like a basic Land or a Sorcery.

When to Play It

This Bird is most effective in decks heavily saturated with artifacts and enchantments to ensure you don't 'miss' on the trigger. Because it costs four hybrid mana, it is exceptionally easy to cast in mono-blue, mono-white, or Azorius decks. It serves as an excellent bridge to your late-game finishers while providing a respectable body to block or chip away at your opponent's life total.

Interaction examples

Doubling the Search

Roaming Throne

If you have Roaming Throne on the battlefield with 'Bird' chosen as the creature type, Arcanist's Owl will trigger twice when it enters. You will look at the top four cards, potentially take one, then repeat the process with the next four cards.

Finding Utility Creatures

Solemn Simulacrum

When Arcanist's Owl enters, you look at your top four cards and see Solemn Simulacrum. Because Solemn Simulacrum is an Artifact Creature, it is a legal target for the Owl's ability. You reveal it, put it in your hand, and prepare to ramp on your next turn.
