Peregrine Drake + Man-o'-War + Yarok, the Desecrated

Peregrine Drake

Man-o'-War

Yarok, the Desecrated

How it works

1. Cast Peregrine Drake by paying 4.
2. When Peregrine Drake enters the battlefield, it triggers itself twice due to Yarok.
3. Resolve one Peregrine Drake trigger, untapping five lands.
4. Activate those lands by tapping them to add at least 3.
5. Resolve the remaining Peregrine Drake trigger, untapping five lands.
6. Activate those lands by tapping them to add at least 3.
7. Cast Man-o'-War by paying 2.
8. When Man-o'-War enters the battlefield, it triggers itself twice due to Yarokg, returning itself and Peregrine Drake from the battlefield to your hand.
9. Repeat.
10. If you can produce at least one additional mana in step 4, this combo produces infinite mana.
