Abdel Adrian, Gorion's Ward + Flicker + Timeless Witness

Abdel Adrian, Gorion's Ward

Flicker

Timeless Witness

How it works

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

This loop sets up an endless cycle of re-entry by casting Flicker to bounce Abdel Adrian, Gorion's Ward, which in turn triggers his ability to temporarily exile the rest of your board. When Abdel vanishes and returns, Timeless Witness comes back right alongside him to pluck Flicker right back out of your graveyard and into your hand. Meanwhile, Abdel's entry trigger allows you to tuck away any mana-producing permanents you control (alongside Timeless Witness herself), netting you a growing army of 1/1 Soldier tokens and resetting your mana sources with every single iteration.
