If you hold a battlefield at the start of turn, then leave it and move back to conquer it again in the same turn, do you trigger the battlefield's conquest effects again?

Ruling: You cannot conquer a battlefield if you have already held it that turn. Once you've scored a battlefield by holding it, moving back to it later in the same turn does not trigger conquest effects.

Sequence:

• If you hold a battlefield at start of turn, you score it
• If you then leave the battlefield and return to it later that turn
• Even if you win a showdown and gain control, you do not conquer it again
• No conquest effects trigger

Nuances:

• Conquering is a subset of scoring, not a separate mechanic
• This applies even if the battlefield changes control between when you held it and when you return (e.g., through active defender mechanics)
