If Blitzcrank empties a battlefield you control, and you use Ride the Wind to move a unit back to that now-empty battlefield during your opponent's turn, do you score a point for conquering it?

Ruling: Yes, you score a point. Scoring is based on whether you've scored on that battlefield this turn, not whether you controlled it at the start of the turn.

Nuances:

• The video showed a judge error where they incorrectly denied the score
• The incorrect ruling was based on control at start of turn rather than whether scoring had occurred that turn
