Say i have a few creatures and Shirei, Shizo's Caretaker on the battlefield. I have supernatural stamina enchanted on Shirei. I desrtoy all creatures and Stamina brings Shirei back. Would the other creatures I controlled return due to shirei's ability?
EDIT: card tag will not work for supernatural stamina. Fixed. The issue was that there was an extra space before Shirei's closing tag; doing that makes other tags in the same post bug. -MadMage
In this scenario, the cards that the creatures became won't return to the battlefield, since Shirei has left the battlefield along with those creatures. It doesn't matter if the ability granted to Shirei by Supernatural Stamina brings Shirei back to the battlefield, since the new Shirei will be different from the Shirei that left as far as the game is concerned (C.R. 400.7).
