Cast Siren's Ruse by paying its mana cost, blinking Abdel Adrian.
Abdel Adrian leaves the battlefield, returning Possessed Skaab and all other cards that were exiled with it to the battlefield.
Abdel Adrian and Possessed Skaab trigger.
Resolve the Possessed Skaab trigger, returning Siren's Ruse 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 Siren's Ruse.
Resolve the Abdel Adrian trigger, exiling Possessed Skaab 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 relies on Abdel Adrian, Gorion's Ward to continuously cycle your nonland permanents in and out of exile, generating an endless army of Soldier tokens while fueling your mana sources. By casting Siren's Ruse to blink Abdel Adrian, you trigger both his own entry effect and Possessed Skaab, whose graveyard-retrieval ability plucks the very same instant right back to your hand. As Abdel Adrian re-enters and devours the Skaab along with your tapped mana producers, you reset the board state for the next iteration—all while Possessed Skaab's replacement effect safely tucks it into exile instead of the graveyard, keeping the engine primed and ready to repeat.
