This clever loop relies on `Peregrine Drake` to generate a surplus of mana every time it enters the battlefield by untapping your lands, while `Warden of the Eye` acts as your recursive engine to continuously fish `Displace` right back out of your graveyard. By casting `Displace` to blink both creatures simultaneously, you reset their enter-the-battlefield triggers to pay for the spell and return it, creating an engine that floods your mana pool and repeats indefinitely.
