Feldon of the Third Path + Worldgorger Dragon + The Peregrine Dynamo + Cyclops of Eternal Fury

Feldon of the Third Path

Worldgorger Dragon

The Peregrine Dynamo

Cyclops of Eternal Fury

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 ingenious loop begins when Feldon of the Third Path targets Worldgorger Dragon in your graveyard, instantly doubled by The Peregrine Dynamo to yield overlapping dragon tokens. As each Worldgorger Dragon token enters the battlefield, its ability exiles all your other permanents—including Feldon of the Third Path and The Peregrine Dynamo—which immediately causes that token to leave the battlefield and return everything to play fresh and untapped. Because Cyclops of Eternal Fury grants all your creatures haste, Feldon of the Third Path can safely repeat this cycle indefinitely alongside any lands or mana producers you control, generating infinite enters-and-leaves-the-battlefield triggers and unbounded mana.
