Kate Stewart + Intruder Alarm + Hourglass of the Lost + Mishra, Eminent One

Kate Stewart

Intruder Alarm

Hourglass of the Lost

Mishra, Eminent One

How it works

1. At the beginning of your combat phase, Mishra triggers, creating a token copy of Hourglass of the Lost that is a 4/4 artifact creature named Mishra's Warform with haste.
2. Activate Mishra's Warform's first ability by tapping it, adding and putting a time counter on it.
3. Kate's first ability triggers, creating a 1/1 Soldier creature token.
4. When the Soldier enters, Intruder Alarm triggers, untapping all creatures.
5. Repeat from step 2.

This fascinating assembly turns Mishra, Eminent One into an unexpected engine by animating Hourglass of the Lost into Mishra's Warform at the start of combat. Tapping that animated artifact for mana places a time counter on it, which immediately triggers Kate Stewart to produce a 1/1 Soldier token. Thanks to Intruder Alarm's static ability, that creature entering the battlefield untaps all creatures—including our artifact-creature copy of Hourglass of the Lost—allowing you to repeat the process indefinitely for infinite white mana, infinite Soldier tokens, and an infinitely large attack fueled by Kate Stewart's second ability.
