Peregrine Drake + Shrieking Drake + Delney, Streetwise Lookout

Peregrine Drake

Shrieking Drake

Delney, Streetwise Lookout

How it works

1. Activate up to five lands by tapping them, adding at least 2.
2. Cast Peregrine Drake by paying its mana cost.
3. When Peregrine Drake enters, it triggers twice. Resolve the first trigger, untapping five lands.
4. Holding priority, activate up to five lands by tapping them, adding at least 2.
5. Resolve the second Peregrine Drake trigger, untapping five lands.
6. Cast Shrieking Drake by paying its mana cost.
7. When Shrieking Drake enters, it triggers twice, returning it and Peregrine Drake from the battlefield to your hand.
8. Repeat.

This clever loop turns the enter-the-battlefield trigger of Peregrine Drake into a massive mana-positive engine, thanks to Delney, Streetwise Lookout doubling every low-power creature trigger. With Delney amplifying both the land-untapping power of Peregrine Drake and the self-bounce ability of Shrieking Drake, you can repeatedly reset your board while generating infinite mana of any color your lands can produce. Shrieking Drake easily hops back to your hand by targeting itself or the Peregrine Drake, ensuring the loop can be replayed indefinitely to fuel an arbitrarily large storm count and infinite creature triggers.
