Does Orange Volibear draw 1 card per character that moves, or 1 card per movement action (if 4 units move to another battlefield simultaneously, is it 1 card or 4 cards)?

Ruling: Orange Volibear draws 1 card per movement action, not per unit. If 4 units move to another battlefield at the same time, you draw 1 card total because the card says "opponent" not "unit".

Nuances:

• Volibear must be at a battlefield to trigger this ability. If he's in base, there is no "battlefield other than his" so the ability doesn't trigger.
