After you buy all Kais from baba shop, just wait. Occasionally Bandai will restart the shop and the Kais will be available to buy again. When? Maybe 300 million downloadd event, or game birthday etc

Anothet source of Kais is sometimes summon events will bonus 2 Kais. Usually happen on mono summons, just wait until these summons pop up

Another source is Kai summons (i.e. you dony summon cards, but Kai only) but extremely rare.

Training location doesn't affect SA rate.
