Intruder Alarm

First Day of Class

How it works

1. Cast First Day of Class by paying 1.
2. Cause a creature to enter the battlefield.
3. Intruder Alarm and First Day of Class trigger.
4. Resolve the Intruder Alarm trigger, untapping all creatures.
5. Holding priority, activate a mana-producing creature by tapping it, adding at least 1.
6. Resolve the First Day of Class trigger, putting a +1/+1 counter on the creature that entered the battlefield.
7. Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
8. Repeat from step 3.
