How it works
Activate Hourglass of the Lost's first ability by tapping it, adding and putting a time counter on it.
Kate's first ability triggers, creating a 1/1 Soldier creature token.
When the Soldier enters, Intruder Alarm triggers, untapping all creatures.
Repeat
By turning Hourglass of the Lost into a 5/5 creature with Ensoul Artifact, you unlock a brilliant loop that starts when you tap the hourglass for mana and a time counter. This triggers Kate Stewart to create a Soldier token, which immediately causes Intruder Alarm to untap all creatures—including your animated Hourglass of the Lost—allowing you to repeat the process endlessly for infinite white mana, infinite tokens, and an infinitely large attack fueled by all those accumulated time counters.
