Leyline Binding 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
Flash Domain — This spell costsless to cast for each basic land type among lands you control. When this enchantment enters, exile target nonland permanent an opponent controls until this enchantment leaves the battlefield.
Complete guide
Leyline Binding is a versatile white enchantment that highlights the power of the Domain mechanic. With the ability to flash onto the battlefield for as little as one white mana, it provides efficient answers to almost any nonland threat. Understanding how its cost reduction and exile duration work is key to mastering this modern staple.
Efficiency Through Domain
The mana cost of Leyline Binding is significantly impacted by the basic land types you control: Plains, Island, Swamp, Mountain, and Forest. For every unique type represented on your battlefield, the generic mana cost is reduced by {1}. While its mana value remains 6, you can frequently cast it for a single white mana if you have a diverse land base.
Exile and Return Mechanics
When Leyline Binding enters the battlefield, its triggered ability targets a nonland permanent an opponent controls. This permanent is exiled immediately upon resolution. Unlike older cards with two separate abilities, this is a single ability that creates a duration. The moment Leyline Binding leaves the battlefield, the exiled card returns to the battlefield under its owner's control.
Interaction Nuances
If Leyline Binding leaves the battlefield before its enters-the-battlefield ability resolves, the target permanent is never exiled at all. Additionally, because the return effect is a one-shot effect that happens instantly, it does not use the stack and cannot be responded to. Remember that any counters on the target permanent are lost when it is exiled, and Auras attached to it will go to the graveyard.
When to Cast
Because of Flash, Leyline Binding is best used during your opponent's turn to disrupt their strategy or remove a surprise attacker. It is also an excellent defensive tool in enchantment-heavy decks, providing both removal and board presence at instant speed.
Interaction examples
Sphere of SafetyIf you have Sphere of Safety on the battlefield, casting Leyline Binding at flash speed increases your enchantment count by one. This immediately increases the cost your opponent must pay to attack you, potentially stopping an alpha strike while also exiling their most dangerous creature.
Cathars' CrusadeIf your opponent controls a creature that has been buffed by Cathars' Crusade, using Leyline Binding to exile it will cause all +1/+1 counters on that creature to cease to exist. Even if the enchantment is later destroyed and the creature returns, it will return as a fresh object with no counters.

Auras attached to the exiled permanent will be put into their owners' graveyards. Equipment attached to an exiled creature will become unattached and remain on the battlefield. Any counters on the exiled permanent will cease to exist.
No other card is named in this ruling.
- #5· Wizards of the Coast
In a multiplayer game, if Leyline Binding's owner leaves the game, the exiled card will return to the battlefield. Because the one-shot effect that returns the card isn't an ability that goes on the stack, it won't cease to exist along with the leaving player's spells and abilities on the stack.
No other card is named in this ruling.
- #6· Wizards of the Coast
Leyline Binding's last ability is a single ability that creates two one-shot effects: one that exiles the permanent when the ability resolves, and another that returns the exiled card to the battlefield immediately after Leyline Binding leaves the battlefield.
No other card is named in this ruling.
