When All-Fates Stalker enters the battlefield, it triggers, exiling Abdel Adrian.
Abdel Adrian leaves the battlefield, causing Icewind Stalwart to return to the battlefield from exile.
When Icewind Stalwart enters the battlefield, it triggers, blinking All-Fates Stalker.
All-Fates Stalker leaves and enters the battlefield, triggering All-Fates Stalker's first and second abilities.
Resolve the second All-Fates Stalker trigger, returning Abdel Adrian from exile to the battlefield.
When Abdel Adrian enters the battlefield, it triggers, exiling Icewind Stalwart and creating a 1/1 Soldier creature token.
Resolve the All-Fates Stalker trigger from step 5, exiling Abdel Adrian until All-Fates Stalker leaves the battlefield.
Repeat from step 3.
This clever loop sets up an infinite cycle of entrances and exits by juggling Abdel Adrian, Gorion's Ward and All-Fates Stalker against each other in a perpetual blinking dance. While the steps focus on the mechanical bounce of All-Fates Stalker and the creature it brings back (referred to in the sequence by its other printing name, Icewind Stalwart), Wispweaver Angel sits in the background ready to support your engine. As the loop spins, Abdel Adrian repeatedly enters the battlefield to spawn an endless army of 1/1 white Soldier creature tokens while triggering infinite leaves-the-battlefield and enters-the-battlefield events for your permanents.
