Quick question about Tamoko Sensei,
The bow ability can it be used when there are no personalities under your opponents control? Basically, I am wondering if It can be used on a turn someone will play a personality or does the personality need to have been in play since the start of the turn?
Also, with the card Your Past which allows you to use Tamoko Sensei's ability an second time. How limiting is the word second. can you play multiple Your Past to use the Sensei three or four times in a turn?

If your opponent controls no Personalities, the condition at the start of Tamoko Sensei's ability is not satisfied, so you may not announce the action. See Good Faith Rule: To legally announce an action, a player must be able to: 3. meet the conditions of any phrase beginning with “If” that starts the action’s effects (such as “If you are the Attacker, …”).
Multiple uses of Your Past do not permit you to use the ability more than twice. See Numbers of Things: Something that allows a “second” use of an ability in a turn, etc., only allows the second use of the ability that turn. Multiple effects that allow second uses do not allow the ability to be used three or more times.
