If you move a unit off a battlefield you already scored this turn and move a unit back in, does it count as a conquer for 'when you conquer' effects?

Ruling: No, it does not count as a conquer for triggering 'when you conquer' effects. You can only score a battlefield once per turn, so moving back onto it does not count as conquering it again.

Nuances:

• This remains true even if your opponent conquered the battlefield after you scored it and you retake it on the same turn - you still don't conquer it again for triggering effects.
