Lyse Hext — ruling 1

Noncreature spells that were cast before Lyse Hext entered count. For example, if Lyse Hext enters on a turn where you've already cast two noncreature spells, she'll have double strike immediately.

Lyse Hext — ruling 2

To determine the total cost of a spell, start with the mana cost or alternative cost you're paying (such as a flashback cost), add any cost increases (such as kicker costs), then apply any cost reductions (such as that of Lyse Hext's second ability). The mana value of the spell is determined by only its mana cost, no matter what the total cost to cast that spell was.

Lyse Hext — ruling 3

The cost reduction applies only to generic mana in the total cost of noncreature spells you cast.

Lyse Hext : règles, fonctionnement et interactions (MTG)

Lyse Hext 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

Prowess (Whenever you cast a noncreature spell, this creature gets +1/+1 until end of turn.) Noncreature spells you cast cost less to cast. As long as you've cast two or more noncreature spells this turn, Lyse Hext has double strike.

Complete guide

Lyse Hext is a formidable Legendary Rebel Monk that provides both mana efficiency and offensive pressure in a single package. By reducing the cost of your noncreature spells and growing stronger with every cast, she quickly becomes a threat that demands an answer. Mastering her timing is key to unlocking her full potential on the battlefield.

A Beacon of Efficiency

Lyse Hext functions as a powerful cost reducer for all noncreature spells you cast, including artifacts, enchantments, sorceries, instants, and planeswalkers. This reduction applies to the total cost of the spell, meaning it can reduce generic mana requirements from the base cost or even additional costs like kicker. Note that this only reduces generic mana; it cannot satisfy colored mana requirements.

Double Strike Activation

Lyse gains double strike as a static ability as long as you have cast two or more noncreature spells during the current turn. It does not matter if Lyse was on the battlefield when those spells were cast. If you cast two sorceries and then cast Lyse, she enters the battlefield with double strike already active. This counts all noncreature spells, even those that were countered or had their costs reduced by her own ability.

Common Mistakes

Players often forget that Lyse Hext is a creature herself, so her cost reduction does not apply to her own mana cost or other creature spells. Additionally, the prowess trigger happens whenever you cast a noncreature spell, regardless of whether that spell resolves. However, the cost reduction is only active while Lyse is on the battlefield; you cannot use her ability to reduce the cost of a spell that you are casting simultaneously with her unless she is already in play.

Strategic Timing

To maximize Lyse, sequence your turns to ensure you can cast at least two cheap noncreature spells before your combat phase. This ensures she has both the prowess buffs and double strike before damage is dealt. Using cheap artifacts or instants allows you to trigger her abilities while keeping mana open for protection.

Interaction examples

Creature Limitations

Solemn Simulacrum

If you attempt to cast Solemn Simulacrum while Lyse Hext is on the battlefield, the cost will not be reduced. Because Solemn Simulacrum is a creature spell, it does not benefit from Lyse's cost reduction ability, nor will it trigger her prowess or count toward the two spells needed for double strike.

Doubling Down on Prowess

Roaming Throne

If you have Roaming Throne on the battlefield and chose 'Human', 'Rebel', or 'Monk' as it entered, Lyse Hext's prowess ability will trigger twice every time you cast a noncreature spell. While the cost reduction and double strike check are static and don't double, the prowess triggers are triggered abilities that the Throne will duplicate, making Lyse twice as large with every spell cast.
