Felidar Guardian + Reveillark + Blasting Station

Felidar Guardian

Reveillark

Blasting Station

How it works

1. Cast Felidar Guardian by paying 3.
2. When Felidar Guardian enters the battlefield, it and Blasting Station trigger, with Felidar Guardian targeting Reveillark.
3. Resolve the Blasting Station trigger, untapping it.
4. Holding priority, activate Blasting Station by tapping it and sacrificing Felidar Guardian.
5. Resolve the Felidar Guardian trigger, blinking Reveillark.
6. Reveillark leaves and enters the battlefield, triggering it and Blasting Station, with Reveillark targeting Felidar Guardian and up to one other creature with power 2 or less from your graveyard to the battlefield.
7. Resolve the Blasting Station trigger, untapping it.
8. Resolve the Reveillark trigger, returning Felidar Guardian and up to one other creature with power 2 or less from your graveyard to the battlefield.
9. Repeat from step 2.

This elegant loop relies on Felidar Guardian's entry trigger to repeatedly cycle Reveillark in and out of play, taking advantage of Reveillark's leave-the-battlefield ability to pull Felidar Guardian right back from the graveyard. Meanwhile, Blasting Station acts as both the engine and the win condition, using its passive untap trigger whenever a creature enters to keep pace with the sacrifices while burning down your opponents one damage at a time.
