After Yasuo's attack trigger kills the defending unit during a showdown, does focus pass to the opponent before scoring?

Ruling: Yes, focus passes to your opponent after Yasuo's attack trigger resolves and kills the defending unit, giving them an opportunity to use actions before you score the point.

Sequence:

• Yasuo attacks and the attack trigger resolves, killing the defending Deadbloom Predator
• Focus passes to the opponent
• Opponent gets opportunity to use actions (like Rebuke)
• After both players pass, the showdown ends and scoring occurs

Nuances:

• You can use Ride the Wind to move Yasuo back to base before your opponent gets focus, but then you won't have any units at the battlefield when the showdown ends and cannot score
• You score by having the only unit(s) after a showdown ends, not simply by being the only one with a unit at a battlefield at any point during the showdown
