Can you win the game by moving a champion from one battlefield to another (using Ganking and Mistfall) to conquer both battlefields in one turn when at 7 points?

Ruling: Yes, you can win by scoring on both battlefields in one turn. When you move a champion from one battlefield to another and conquer the second battlefield, both scores count toward the "all battlefields" win condition even though the first battlefield is no longer occupied.

Sequence:

• First, score the champion onto the first battlefield (Ganking/Windswept) via conquer or hold
• Second, move that champion to the second battlefield and win the showdown
• Score from conquering the second battlefield for the winning point

Nuances:

• If you were at 7 points, you would draw 1 card from scoring on the first battlefield, then win from scoring on the second battlefield
• This works the same way on both your turn and your opponent's turn
• To win on an opponent's turn via conquer, you need to score on all battlefields during that turn (hold points from your previous turn don't count)
