How it works
Activate any number of permanents by tapping them, adding at least 3.
Activate Feldon by paying 2 and tapping it, targeting Worldgorger Dragon.
Holding priority, activate The Peregrine Dynamo by paying 1 and tapping it, copying Feldon's ability targeting Worldgorger Dragon.
Resolve the copy of Feldon's ability, creating a token copy of Worldgorger Dragon.
When the Worldgorger Dragon token enters, its first ability triggers, exiling all other permanents you control.
Resolve the Feldon ability from step 2, creating a token copy of Worldgorger Dragon.
When the Worldgorger Dragon token enters, its first ability triggers, exiling all other permanents you control.
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.
