Detention Sphere

How it works

1. Cast Lumbering Battlement by paying 4.
2. When Lumbering Battlement enters the battlefield, it triggers, exiling Abdel Adrian until Lumbering Battlement leaves the battlefield.
3. Abdel Adrian leaves the battlefield, ending its effect, causing Detention Sphere to return from exile to the battlefield.
4. When Detention Sphere enters the battlefield, its first ability triggers, exiling Lumbering Battlement.
5. Lumbering Battlement 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 Detention Sphere 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. When Detention Sphere leaves the battlefield, its second ability triggers, returning Lumbering Battlement to the battlefield from exile.
8. Repeat from step 2.
