Marang River Regent // Coil and Catch — ruling 1

As a player casts an omen card, the player chooses whether they cast the card normally or as an Omen.

Marang River Regent // Coil and Catch — ruling 2

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.”).

Marang River Regent // Coil and Catch — ruling 3

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.

Marang River Regent // Coil and Catch — ruling 4

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.

Marang River Regent // Coil and Catch — ruling 5

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.

Marang River Regent // Coil and Catch — ruling 6

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.

Marang River Regent // Coil and Catch — ruling 7

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.

Marang River Regent // Coil and Catch — ruling 8

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.

Marang River Regent // Coil and Catch : règles, fonctionnement et interactions (MTG)

Marang River Regent // Coil and Catch 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.

Flying When this creature enters, return up to two other target nonland permanents to their owners' hands. Draw three cards, then discard a card. (Then shuffle this card into its owner's library.)

Complete guide

Marang River Regent // Coil and Catch is a versatile blue card that offers both board control and card filtering. Whether you need a massive flying Dragon to clear the way or a quick burst of fresh cards, this omen card has you covered. By understanding the Omen mechanic, you can maximize your resources and keep your opponents guessing.

Understanding Omens

Marang River Regent is a creature card by default in all zones like your library or graveyard. However, when you cast it, you choose between the creature or the Omen, Coil and Catch. If cast as an Omen, it functions as an instant spell with a mana value of 4. A unique rule for Omens is that they are shuffled into your library as they resolve instead of going to the graveyard, allowing you to potentially draw and cast them again later in the game.

Resolving the Spells

If you cast Marang River Regent, it enters the battlefield as a 4/4 Flying Dragon, and its triggered ability targets up to two other nonland permanents to bounce back to hand. If you cast Coil and Catch, you immediately draw three cards and then discard one. Once the discard is complete, the physical card is shuffled back into your library. Note that if an Omen is countered or its targets (if it had any) become illegal, it goes to the graveyard instead of being shuffled back.

Common Pitfalls

Players often forget that Omens are only instants while on the stack. In your graveyard, Coil and Catch does not exist; only Marang River Regent does. This means you cannot use effects that return instant cards from your graveyard to your hand to retrieve it. Additionally, if an effect like Hullbreaker Horror returns an Omen to your hand while it is on the stack, it does not get shuffled into the library because it never resolved.

When to Play It

Cast the creature side when you need to stabilize the board or remove blockers for a lethal swing. The Omen side is perfect for finding specific answers or refueling your hand during your opponent's end step. Since the Omen shuffles back, it is a great tool for long games where you want to avoid decking out while maintaining card quality.

Interaction examples

Bouncing the Horror

Hullbreaker Horror

You cast Marang River Regent for six mana. It enters the battlefield, and its triggered ability targets your opponent's Hullbreaker Horror. The ability resolves, returning the Horror to its owner's hand, leaving you with a powerful 4/4 flyer on an empty board.

The Crawler's Sting

Psychosis Crawler

With Psychosis Crawler on the battlefield, you cast Coil and Catch as an Omen. As the spell resolves, you draw three cards, triggering the Crawler three times to deal 3 life loss to your opponent. You then discard one card and shuffle Coil and Catch back into your library, ready to be drawn and cast again.
