Cast Siren's Ruse by paying its mana cost, blinking Abdel Adrian.
Abdel Adrian leaves the battlefield, returning Invasion of Arcavios and all other cards that were exiled with it to the battlefield.
Abdel Adrian and Invasion of Arcavios trigger.
Resolve the Invasion of Arcavios 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 Invasion of Arcavios 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 the constant recasting of Siren's Ruse to blink Abdel Adrian, Gorion's Ward over and over. Each time Abdel re-enters, he exiles Invasion of Arcavios along with your mana-producing permanents, which simultaneously triggers the Siege's ability to fetch Siren's Ruse right back out of your graveyard into your hand. This perpetual motion engine not only floods the board with an endless army of Soldier tokens, but it also generates infinite magecraft triggers, storm count, and blinking for all your nonland permanents.
