If a player scores a point at a battlefield on their opponent's turn (e.g., by being charmed there), can the active player still score at that same battlefield later in the same turn?

Ruling: Yes, both players can score at the same battlefield during a single turn. Each player may only score once per battlefield per turn, but this limit applies separately to each player.

Sequence:

• Player A charms Player B's unit to an empty battlefield on Player A's turn
• Player B scores a point for capturing that battlefield
• Player A then conquers that same battlefield later in the same turn
• Player A also scores a point

Nuances:

• Points are never taken away in this game
• The "once per battlefield per turn" restriction applies to each player individually, not to the battlefield itself
