Feldon of the Third Path + Worldgorger Dragon + Fervor + The Peregrine Dynamo

Feldon of the Third Path

Worldgorger Dragon

Fervor

The Peregrine Dynamo

How it works

1. Activate any number of permanents by tapping them, adding at least 3.
2. Activate Feldon by paying 2 and tapping it, targeting Worldgorger Dragon.
3. Holding priority, activate The Peregrine Dynamo by paying 1 and tapping it, copying Feldon's ability targeting Worldgorger Dragon.
4. Resolve the copy of Feldon's ability, creating a token copy of Worldgorger Dragon.
5. When the Worldgorger Dragon token enters, its first ability triggers, exiling all other permanents you control.
6. Resolve the Feldon ability from step 2, creating a token copy of Worldgorger Dragon.
7. When the Worldgorger Dragon token enters, its first ability triggers, exiling all other permanents you control.
8. When the Worldgorger Dragon token created in step 4 leaves the battlefield, its second ability triggers, returning all cards exiled with it to the battlefield.
9. Repeat.

This loop is a masterclass in reanimation, turning Feldon of the Third Path into an engine that repeatedly resurrects Worldgorger Dragon with the help of The Peregrine Dynamo to double up the initial trigger. As each Worldgorger Dragon token enters, it exiles all your other permanents—including your lands, Feldon, and The Peregrine Dynamo—which in turn causes that Dragon to leave the battlefield and return everything untapped. Thanks to Fervor granting all your creatures haste, your permanents are immediately ready to be tapped for mana and activated again right as they reappear. By looping this sequence endlessly, you generate infinite enter-the-battlefield and leave-the-battlefield triggers alongside infinite mana from every land and permanent you control.
