Carte Magic O-Naginata

O-Naginata 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

This Equipment can be attached only to a creature with power 3 or greater. Equipped creature gets +3/+0 and has trample. Equip {2} ({2}: Attach to target creature you control. Equip only as a sorcery.)

Complete guide

O-Naginata is a powerful piece of equipment that provides a massive boost for a very low cost. While it offers efficient stats and evasion, it comes with a specific restriction regarding which warriors are worthy enough to wield it. Understanding how its power requirement interacts with the battlefield is key to maximizing its potential.

Wielding the Great Blade

O-Naginata grants the equipped creature +3/+0 and trample, but it can only be attached to a creature with power 3 or greater. This restriction applies both when you attempt to attach it and while it is already equipped. If the creature's power ever drops below 3, the equipment will immediately fall off.

The Attachment Process

When you activate the equip ability, you must target a creature you control. While the ability can technically target a creature with power 2 or less, the ability will fail to attach O-Naginata upon resolution if the creature's power isn't at least 3. Once attached, the +3/+0 bonus counts toward keeping the requirement met; however, if a reduction effect brings the total power to 2 or less, state-based actions will cause O-Naginata to become unattached.

Strategic Timing

Because the equip ability functions at sorcery speed, you must ensure your creature meets the power requirement during your main phase. If your opponent uses a spell to shrink your creature's power in response to an equip activation, the equipment stays where it was. Similarly, if your creature is weakened during combat, O-Naginata will fall off before damage is dealt if its power drops too low.

Interaction examples

Powering Up the Blade

You have a creature with 3 power on the battlefield. You tap Sol Ring to generate two colorless mana, which is exactly the cost required to activate O-Naginata's equip ability. Since the creature currently has 3 power, the ability resolves successfully, and your creature becomes a 6-power threat with trample.

Fast Mana and Equipment

You use Arcane Signet to produce the mana needed to cast O-Naginata for one mana and later activate its equip ability for two mana. Even if you have the mana ready, remember you cannot attach O-Naginata to a 1/1 token or a 2/2 utility creature, as the equipment requires the base power (plus any other current modifiers) to be at least 3 before the +3/+0 from the Naginata itself is applied.
