Carte Magic Lightning Greaves

Lightning Greaves 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

Equipped creature has haste and shroud. (It can't be the target of spells or abilities.) Equip {0}

Complete guide

Lightning Greaves is a staple of Commander and casual formats, providing essential protection and speed to your most important creatures. This iconic artifact allows you to safeguard your threats for no mana cost once it is on the battlefield. Understanding how to manage its shroud ability is key to mastering its utility.

What it Does

Lightning Greaves is an Equipment that grants two powerful keywords: haste and shroud. Haste allows a creature to attack or use activated abilities with the tap symbol immediately upon entering the battlefield. Shroud ensures the creature cannot be the target of spells or abilities, including your own, which provides a significant layer of defense against removal.

How it Resolves

When you activate the equip ability for {0}, you choose a target creature you control. Upon resolution, the Greaves attach to that creature. The creature immediately gains haste and shroud. Because the equip cost is zero, you can move the Greaves between creatures you control as often as you like during your main phase when the stack is empty, provided you have legal targets.

Common Mistakes

A frequent error involves the 'Haste' keyword and multiple creatures. While you can move the Greaves freely, a creature must actually have haste at the moment it is declared as an attacker. You cannot use one pair of Greaves to give two different 'summoning sick' creatures haste to attack in the same combat phase. Additionally, remember that shroud prevents you from targeting your own creature with combat tricks or other equipment while the Greaves are attached.

When to Play it

This card is best used to protect a 'glass cannon' commander or to enable creatures with powerful tap abilities the moment they arrive. It is also excellent for shifting protection; if you need to target your creature with a buff, you can move the Greaves to a different creature, cast your spell, and then move the Greaves back to restore shroud.

Interaction examples

Fast Mana Setup

On turn one, you play a land and cast Sol Ring. You then use one of the two colorless mana produced by Sol Ring to cast Lightning Greaves. This leaves you with an open board ready to protect your turn-two play immediately without needing further mana investment.

Color Fixing and Protection

If you have Arcane Signet and Lightning Greaves on the field, you can cast your Commander using mana from the Signet. As soon as the Commander enters the battlefield, you can activate the {0} equip ability of the Greaves. This ensures your Commander is protected from targeted removal spells before your opponents even receive priority to act in your main phase.

How it works : Lightning Greaves

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    You can't simply unequip Equipment from a creature. If Lightning Greaves is attached to the only creature you control, you won't be able to attach other equipment to it (or target it with anything else) until you have another creature to which you can attach Lightning Greaves.

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    If a creature enters the battlefield under your control and gains haste, but then loses it before attacking, it won't be able to attack that turn. This means that you can't use one Lightning Greaves to allow two new creatures to attack in the same turn.

    No other card is named in this ruling.
