Abdel Adrian, Gorion's Ward + Phantom Steed + Mirror Image

Abdel Adrian, Gorion's Ward

Phantom Steed

Mirror Image

How it works

1. Cast Phantom Steed by paying 3.
2. When Phantom Steed enters the battlefield, its first ability triggers, exiling Abdel Adrian until Phantom Steed leaves the battlefield.
3. Abdel Adrian leaves the battlefield, ending its effect, causing Mirror Image to return from exile to the battlefield as a copy of Phantom Steed.
4. When Mirror Image enters the battlefield, its first ability triggers, exiling Phantom Steed until Mirror Image leaves the battlefield.
5. Phantom Steed leaves the battlefield, ending its effect, causing Abdel Adrian to return from exile to the battlefield.
6. When Abdel Adrian enters the battlefield, it triggers, exiling Mirror Image and any number of other nonland permanents you control until Abdel Adrian leaves the battlefield and creating at least one 1/1 Soldier creature token.
7. Mirror Image leaves the battlefield, ending its effect, causing Phantom Steed to return to the battlefield from exile.
8. Repeat from step 2.

This loop creates a perpetual motion machine in the Command Zone by cycling our key permanents in and out of exile. It begins when Phantom Steed enters to swallow Abdel Adrian, whose departure immediately triggers the return of Mirror Image; Mirror Image then steps in to exile Phantom Steed, which in turn brings back Abdel Adrian to restart the whole sequence. Because Abdel Adrian's entry trigger also exiles any other nonland permanents you control, you can infinitely cycle your entire board to generate an endless army of Soldier tokens and unlimited enters-the-battlefield triggers.
