Cast Go Ninja Go 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 Go Ninja Go 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 Go Ninja Go.
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 mesmerizing loop revolves around Abdel Adrian, Gorion's Ward, whose entry into the battlefield exiles your other nonland permanents to flood the board with 1/1 Soldier creature tokens. By using Go Ninja Go to blink Abdel Adrian, you trigger a cascading reset that allows Mnemonic Wall to scoop Go Ninja Go right back out of your graveyard and into your hand. Along the way, your mana-producing permanents get swept up in Abdel Adrian's exile ability and recast into play, letting you tap them anew on each iteration to pay for Go Ninja Go's casting cost.
