When an opponent uses Possession on a unit equipped with Guardian Angel, who controls the Guardian Angel, and where does the unit get recalled to if Guardian Angel triggers?

Ruling: When Possession takes control of a unit equipped with Guardian Angel, the original owner retains control of the Guardian Angel equipment, but it remains attached to the possessed unit and continues providing its effect. If Guardian Angel triggers when the unit dies, the unit is recalled to the current controller's (the opponent's) base, and Guardian Angel goes to its owner's (the original player's) trash.

Sequence:

• Opponent uses Possession on your unit equipped with Guardian Angel
• You retain control of Guardian Angel, but it stays attached to the possessed unit
• Guardian Angel continues to give its effect to the possessed unit
• If the unit dies and Guardian Angel triggers, the unit recalls to the opponent's base
• Guardian Angel goes to your trash

Nuances:

• You can use effects like Weaponmaster to move your Guardian Angel to one of your own units while it's attached to the possessed unit
• You cannot use Guardian Angel's own equip ability while it's already attached to a unit
• Equipment loses its bottom text box when equipped and loses its top text box when unequipped
