When Yasuo's ability is on the chain and the opponent removes Yasuo with Hidden Blade before the ability resolves, does the ability still deal damage based on Yasuo's might?

Ruling: Yasuo's ability would not deal damage if Yasuo is removed from the battlefield before the ability resolves. The might value cannot be determined when the unit is no longer present.

Nuances:

• The ability does null damage (not 0 damage), which is an important distinction for interactions with cards like Void Gate that care about the difference between null damage and 0 damage.
