If I control Volibear (Imposing) at Battlefield A and use Charm to move my opponent's Stalwart Poro to Battlefield B, will I draw a card?

Ruling: Yes, you will draw a card. Under current rulings, "When an opponent moves to a battlefield" is treated as "Whenever one or more enemy units move to a battlefield." Since the enemy unit moved to a battlefield other than the one Volibear occupies, his Imposing ability triggers and you draw one card.

Sequence:

• You cast Charm targeting the opponent's unit
• The enemy unit moves to Battlefield B (different from Volibear's Battlefield A)
• Volibear's Imposing ability triggers
• You draw 1 card

Nuances:

• You only draw one card per move action, regardless of how many units are moved simultaneously
• The ability only triggers when enemy units move to a battlefield OTHER than the one Volibear currently occupies
• It doesn't matter who performs the move action (you or your opponent); what matters is that an enemy unit moved
