Abdel Adrian, Gorion's Ward + Mnemonic Wall + Justiciar's Portal

Abdel Adrian, Gorion's Ward

Mnemonic Wall

Justiciar's Portal

How it works

1. Cast Justiciar's Portal by paying its mana cost, blinking Abdel Adrian.
2. Abdel Adrian leaves the battlefield, returning Mnemonic Wall and all other cards that were exiled with it to the battlefield.
3. Abdel Adrian and Mnemonic Wall trigger.
4. Resolve the Mnemonic Wall trigger, returning Justiciar's Portal from your graveyard to your hand.
5. Holding priority, activate any number of nonland permanents you control by tapping them, adding at least enough mana to cast Justiciar's Portal.
6. 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.
7. Repeat.
