Activate Go-Shintai by paying and tapping it, returning any Shrine from your graveyard to the battlefield.
The Shrine enters the battlefield, triggering Go-Shintai, creating a 1/1 Shrine enchantment creature token.
The Shrine token enters the battlefield, triggering Intruder Alarm, untapping all creatures.
