Can you win the game by scoring your 8th point through an alternative win condition (like Yasuo Windrider) without controlling both battlefields?

Ruling: Yes, you can score the 8th point and win through alternative win conditions like Yasuo Windrider, Tryndamere, or Ahri without controlling both battlefields.

Nuances:

• Needing control of both battlefields to win is a misconception
• To win by conquer specifically (when the 2nd battlefield counts), you must have scored both battlefields, not necessarily control them at the moment of winning
• Only one showdown can occur at a time; a current showdown must fully resolve before a new showdown can begin
