If a unit is stunned during combat and then moved to another battlefield, does it remain stunned or can it deal damage in the new combat?

Ruling: A stunned unit remains stunned for the entire turn, even if moved to a different battlefield. The Stun status lasts until the beginning of the next Ending Step (end of turn).

Nuances:

• Even though a stunned unit cannot attack or block, Yasuo's ability can still trigger and deal damage when he attacks, so he can still win combat when attacking despite being stunned.
