Rodolf Duskbringer + The Peregrine Dynamo + Ashnod's Altar

Rodolf Duskbringer

The Peregrine Dynamo

Ashnod's Altar

How it works

1. At the beginning of your end step, Rodolf Duskbringer triggers, allowing you to pay 1W/B.
2. When you do, put Rodolf Duskbringer's ability on the stack targeting any creature in your graveyard.
3. Holding priority, activate The Peregrine Dynamo by paying 1 and tapping it, targeting Rodolf Duskbringer's ability.
4. Holding priority again, activate Ashnod's Altar by sacrificing The Peregrine Dynamo, adding 2.
5. Resolve The Peregrine Dynamo's ability, copying Rodolf Duskbringer's ability targeting The Peregrine Dynamo.
6. Resolve the copied ability, returning The Peregrine Dynamo from your graveyard to the battlefield.
7. Repeat from step 3.
