How it works
Activate Fain's third ability by tapping it and sacrificing another artifact, creating a 2/1 Inkling creature token.
When the Inkling enters the battlefield, Intruder Alarm triggers, untapping all creatures.
Activate Phantom Train by sacrificing the Inkling.
When the Inkling dies, Pitiless Plunderer triggers, creating a Treasure token.
