Abdel Adrian, Gorion's Ward + Phantom Steed + Clever Impersonator

Abdel Adrian, Gorion's Ward

Phantom Steed

Clever Impersonator

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 Clever Impersonator to return from exile to the battlefield as a copy of Phantom Steed.
4. When Clever Impersonator enters the battlefield, its first ability triggers, exiling Phantom Steed until Clever Impersonator 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 Clever Impersonator 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. Clever Impersonator leaves the battlefield, ending its effect, causing Phantom Steed to return to the battlefield from exile.
8. Repeat from step 2.

This loop relies on a brilliant cascading exile cycle between Abdel Adrian, Gorion's Ward and Phantom Steed, where Clever Impersonator steps in as a shape-shifting catalyst to keep the dance going. When Abdel Adrian enters the battlefield, he exiles the Steed-copy Impersonator along with any other nonland permanents you wish to blink, returning the original Phantom Steed to the field. That fresh Phantom Steed immediately exiles Abdel Adrian in turn, which releases Clever Impersonator right back to the battlefield so it can copy the Steed once more and restart the entire sequence. Through this perpetual motion machine, you not only generate an infinite number of 1/1 Soldier tokens from Abdel Adrian's repeated entries, but you also achieve endless enters-the-battlefield and leaves-the-battlefield triggers for every other nonland permanent you manage to catch in the crossfire.
