Felidar Guardian + Reveillark + Yahenni, Undying Partisan

Felidar Guardian

Reveillark

Yahenni, Undying Partisan

How it works

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

This cunning loop turns the battlefield into a revolving door by leveraging Felidar Guardian's entry trigger to blink Reveillark, which in turn brings Felidar Guardian right back from the graveyard when it leaves. While Reveillark provides the crucial recursion engine for creatures with power 2 or less, Yahenni, Undying Partisan acts as the perfect sacrifice outlet to kick off the cycle on command. Together, they create an endless loop of sacrifices and triggers that can be repeated indefinitely to fuel your victory.
