Can you move a unit with Yasuo's legend ability and another unit with normal movement at the same time to start a showdown with both?

Ruling: No, you cannot move units together using Yasuo's legend ability and normal movement simultaneously. Moving units together is only possible with the standard move action.

Nuances:

• Yasuo's legend ability does not allow combining its movement with other movement types
• Only the standard move action permits moving multiple units together
