Cast Slip On the Ring by paying its mana cost, blinking Abdel Adrian.
Abdel Adrian leaves the battlefield, returning Ardent Elementalist and all other cards that were exiled with it to the battlefield.
Abdel Adrian and Ardent Elementalist trigger.
Resolve the Ardent Elementalist trigger, returning Slip On the Ring from your graveyard to your hand.
Holding priority, activate any number of nonland permanents you control by tapping them, adding at least enough mana to cast Slip On the Ring.
Resolve the Abdel Adrian trigger, exiling Ardent Elementalist and the mana-producing permanents until Abdel Adrian leaves the battlefield, and creating a 1/1 Soldier creature token for each permanent exiled this way.
Repeat.
This clever loop hinges on Abdel Adrian, Gorion's Ward endlessly cycling in and out of exile to fuel an unstoppable engine of creation. By casting Slip On the Ring to blink Abdel Adrian, you trigger a cascade where Ardent Elementalist is repeatedly returned to hand-deliver the very same spell right back to your grasp. Along the way, Abdel Adrian's entrance scoops up your other mana-producing permanents only to drop them back onto the battlefield, letting you tap them for the mana needed to keep the cycle spinning while generating an overwhelming horde of Soldier tokens.
