If I move a ready unit from my base to a battlefield using Yasuo's Legend ability, does the unit become exhausted?

Ruling: When you move a unit with Yasuo's ability, the unit stays ready. Exhausting a unit is a cost to perform a standard move; any other form of movement doesn't exhaust unless stated.

Nuances:

• You can move an exhausted unit with Yasuo
• Ganking units do exhaust when they move because ganking is just a modification to the standard move, so they're still using the inherent move effect
• You cannot score the same battlefield twice in the same turn, but you can score two separate battlefields in one turn
