Carte Magic Tidal Courier

Tidal Courier 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.

01

Official card text

When this creature enters, reveal the top four cards of your library. Put all Merfolk cards revealed this way into your hand and the rest on the bottom of your library in any order. {3}{U}: This creature gains flying until end of turn.

Complete guide

Tidal Courier is a versatile Merfolk scout that helps you dig deep into your library to find your aquatic allies. Not only does it provide card advantage upon arrival, but it can also take to the skies to bypass ground defenses. Whether you are building a dedicated tribal deck or a tempo-based strategy, understanding how its entry ability and activated ability function is key.

Sifting the Tides

When Tidal Courier enters the battlefield, its triggered ability immediately goes on the stack. You reveal the top four cards of your library. Any card with the 'Merfolk' creature type is moved to your hand, while all other cards—including lands, spells, or other creature types—are placed on the bottom of your library in the order of your choice.

Taking Flight

For three generic and one blue mana, you can activate Tidal Courier's second ability to give it flying until the end of the turn. This is an activated ability that can be used at instant speed, allowing you to react to blockers or activate it during your own turn to strike from the air.

Common Mistakes

A frequent error is forgetting that the cards not chosen go to the bottom of the library rather than the graveyard. Additionally, the reveal effect is mandatory once the creature enters, but you do not have to pay the mana for flying unless you want the keyword. Remember that if the Courier is destroyed in response to its entry trigger, you still reveal the top four cards.

When to Play It

Tidal Courier is best played when you have several Merfolk cards remaining in your library to maximize the chance of drawing multiple cards. In combat, hold your mana open for the flying activation to force your opponent into difficult blocking decisions.

Interaction examples

Doubling the Catch

If you control Roaming Throne and have chosen 'Merfolk', Tidal Courier's entry ability will trigger an additional time. You will reveal the top four cards, put Merfolk into your hand, then immediately repeat the process for the next four cards, potentially drawing up to eight cards total.

Sequencing Entries

If you cast Solemn Simulacrum first, you search your library and shuffle. This ensures your library is randomized before Tidal Courier enters. If you play Tidal Courier and see non-Merfolk cards you dislike, they go to the bottom; playing the Simulacrum afterwards would shuffle those unwanted cards back into the main library.
