• 8/7/2020 O-Naginata can become attached to a creature only if that creature’s power is 3 or greater before O-Naginata is attached to it.
• 8/7/2020 O-Naginata’s equip ability can target any creature you control—but if the creature’s power is 2 or less, it won’t become attached as it resolves.
• 8/7/2020 O-Naginata becomes unattached if the equipped creature’s power is reduced so that its power is 2 or less, including the +3/+0 from O-Naginata’s effect, as state-based actions are checked.
