Does moving a unit to a battlefield you already control start a showdown? Can you re-conquer a battlefield you already scored from to trigger on-conquer effects?

Ruling: Moving a unit to a battlefield you already control does not start a showdown. You cannot re-conquer a battlefield you have already scored from this turn to trigger on-conquer effects.

Sequence:

• When you contest a battlefield and win the showdown, you gain control
• If you have not scored on that battlefield this turn (either from holding or a conquer), the game state also adds conquered status on top of control, which gives you the +1 score
• If you move back and win the showdown again, you only get control again but conquer does not happen because you already scored
• Without the conquer status, on-conquer abilities do not trigger

Nuances:

• You can only score 1 point per battlefield per turn
• Scoring is part of the requirement for conquer
• The exception is when you are at 7 points and cannot score off that conquer, where you draw the card instead
