Can you hold a battlefield with Monastery, move all units off, then conquer it again in the same turn to trigger Monastery's draw effect?

Ruling: No, you cannot conquer a battlefield you held that turn. Both holding and conquering are types of scoring, and you can only score each battlefield once per turn.

Nuances:

• Holding and conquering are different types of scoring, but both count as scoring the battlefield
• Conquering only happens when you haven't scored the battlefield that turn
