One ruling from Wizards of the Coast
- 16 March 2018If Stangg leaves the battlefield before its ability has resolved, that ability will still create a Stangg Twin token, but its delayed triggered ability that exiles the token will never have a chance to trigger. That token will remain on the battlefield.
