In a Free For All game, if I use Charm to move an opponent's unit into another opponent's battleground during my turn, can the Charmed unit's owner score the winning point from that conquer if they were already holding another battleground?

Ruling: No, the opponent cannot score the winning point from conquering during your turn. Players only Hold battlegrounds on their own turns, not on opponent's turns, so conquering via Charm causes them to draw a card instead of scoring a point.

Sequence:

• The Charmed unit conquers a battleground on your turn (opponent draws 1 card instead of getting a point)
• On the opponent's next turn, they lose and regain control of their battleground to conquer it again (draws 1 card instead of getting a point)
• The opponent conquers a third battleground to finally score the winning point

Nuances:

• Even if an opponent was holding another battleground before your turn, they do not Hold it during your turn
• Conquering battlegrounds on an opponent's turn results in drawing cards instead of scoring points
