Dazzling Theater // Prop Room + Intruder Alarm + Spider-Byte, Web Warden

Dazzling Theater // Prop Room

Intruder Alarm

Spider-Byte, Web Warden

How it works

1. Cast Spider-Byte by tapping a number of creatures and paying 0.
2. When Spider-Byte enters the battlefield, it and Intruder Alarm trigger.
3. Resolve the Spider-Byte trigger, returning it from the battlefield to your hand.
4. Resolve the Intruder Alarm trigger, untapping all creatures.
5. Repeat.

This fascinating loop turns Dazzling Theater // Prop Room's passive enchantment half—specifically its room ability granting creature spells convoke—into an engine of perpetual motion. Because Intruder Alarm ensures creatures stay locked down normally, it instead relies on its triggered ability to untap your entire board every time a creature enters the battlefield. This allows you to continually tap your freshly untaped creatures to pay for Spider-Byte, Web Warden, whose own entry trigger bounces itself right back to your hand while simultaneously satisfying Intruder Alarm's condition.
