Idris, Soul of the TARDIS + Intruder Alarm + Myr Turbine

Idris, Soul of the TARDIS

Intruder Alarm

Myr Turbine

How it works

1. Activate Idris using Myr Turbine's first ability by tapping it, creating a 1/1 Myr artifact creature token.
2. When the Myr enters the battlefield, Intruder Alarm triggers, untapping all creatures.
3. Repeat.
4. Once you control five or more Myrs, you may instead use Myr Turbine's second ability until all Myrs in your library are put onto the battlefield.

This intricate sequence hinges on Idris, Soul of the TARDIS copying Myr Turbine's activated abilities while the artifact itself is safely tucked away in exile. Because Idris inherits those tap abilities, it can repeatedly stamp out 1/1 Myr artifact creature tokens. Each token's arrival triggers Intruder Alarm, which smartly untaps all creatures—including your industrious Idris—so you can tap it right back down to start the loop over again. Once you have built up a sufficient army, you can leverage that same untap engine and Myr Turbine's second ability to tutor every single Myr creature straight out of your library and onto the battlefield.
