One ruling from Wizards of the Coast
- 18 July 2014If Yisan isn't on the battlefield when its ability resolves, use the number of verse counters on it when it left the battlefield to determine which creature cards may be put onto the battlefield. This number will include the counter you put on Yisan to activate the ability.
