Tawnos, Solemn Survivor + Intruder Alarm + Priest of Urabrask

Tawnos, Solemn Survivor

Intruder Alarm

Priest of Urabrask

How it works

1. Activate Tawnos' second ability by paying 1, sacrificing two artifact tokens, and exiling Priest of Urabrask from your graveyard, creating a token copy of Priest of Urabrask that is an artifact in addition to its other types.
2. The Priest of Urabrask token enters the battlefield, triggering itself and Intruder Alarm.
3. Resolve the Priest of Urabrask trigger, adding .
4. Resolve the Intruder Alarm trigger, untapping all creatures.
5. Activate Tawnos' first ability by paying 2 and tapping it, creating a token copy of the Priest of Urabrask token, and causing you to mill two cards.
6. Repeat from step 2.
7. Once you have infinite red mana, you may instead choose any other artifact token(s) to make infinite copies of them.
