This loop is a masterclass in recursive value, turning a single instant into an infinite engine by leveraging exact mana math. You cast **Displace** to blink both **Shipwreck Dowser** and **Great Whale** at the same time, spending the mana generated by tapping your lands. When **Great Whale** hits the battlefield, its enters-the-battlefield trigger untaps up to seven of those lands, more than paying for the spell you just cast, while **Shipwreck Dowser** triggers to fish **Displace** right back out of your graveyard. Thanks to **Shipwreck Dowser**'s prowess ability, you even get an infinitely growing creature alongside your infinite mana, storm count, and blinking loops in Commander, Legacy, Oathbreaker, and Vintage!
