If you start your turn holding 1 battlefield (reaching 7 points), then lose control of it but take the other battlefield during the same turn, do you still win?

Ruling: Yes, this is a win. You do not need to actively hold both battlefields simultaneously to score the final point via conquest.

Sequence:

• Start turn holding 1 battlefield, gaining a point (reaching 7)
• Lose control of that battlefield during your turn
• Take control of the other battlefield during the same turn
• Win condition is met

Nuances:

• You only need to have scored both battlefields at some point during that turn, not hold them simultaneously
