Cast Another Round by paying its mana cost, blinking Abdel Adrian.
Abdel Adrian leaves the battlefield, returning Mnemonic Wall and all other cards that were exiled with it to the battlefield.
Abdel Adrian and Mnemonic Wall trigger.
Resolve the Mnemonic Wall trigger, returning Another Round 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 Another Round.
Resolve the Abdel Adrian trigger, exiling Mnemonic Wall 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 swallow up your own board and spit it back out, fueled by Another Round's ability to repeatedly blink your creatures. Every iteration relies on Mnemonic Wall entering the battlefield to scoop Another Round right back out of your graveyard and into your hand, ensuring you never run out of gas. Meanwhile, Abdel Adrian's exile effect conveniently allows you to reset mana-producing permanents so you can tap them again each cycle, ultimately flooding the board with an endless army of Soldier tokens while generating infinite storm and magecraft triggers along the way.
