Can you score your 8th point by using Ride the Wind to move to a second battlefield on your opponent's turn if you already control one battlefield and have 7 points?

Ruling: No, you cannot score the 8th point this way. You must score both battlefields within the same turn to reach the 8th point.

Nuances:

• You could theoretically win on an opponent's turn by conquering both battlefields during their turn if you started with 0 controlled battlefields
• You can use Ride the Wind to leave and reconquer the same battlefield to draw a card and score a point (just not to reach the 8th point from controlling two different battlefields across different turns)
