Abdel Adrian, Gorion's Ward + Eternal Witness + Go Ninja Go

Abdel Adrian, Gorion's Ward

Eternal Witness

Go Ninja Go

How it works

1. Cast Go Ninja Go by paying its mana cost, blinking Abdel Adrian.
2. Abdel Adrian leaves the battlefield, returning Eternal Witness and all other cards that were exiled with it to the battlefield.
3. Abdel Adrian and Eternal Witness trigger.
4. Resolve the Eternal Witness trigger, returning Go Ninja Go 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 Go Ninja Go.
6. Resolve the Abdel Adrian trigger, exiling Eternal Witness 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.
