When Touch the Spirit Realm enters the battlefield, it triggers, exiling Lumbering Battlement until Touch the Spirit Realm leaves the battlefield.
Lumbering Battlement leaves the battlefield, ending its effect, causing Abdel Adrian to return from exile to the battlefield.
When Abdel Adrian enters the battlefield, it triggers, exiling Touch the Spirit Realm 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.
Touch the Spirit Realm leaves the battlefield, ending its effect, causing Lumbering Battlement to return to the battlefield from exile.
Repeat from step 2.
This loop achieves infinite blinking and an endless army of tokens by trading places in an endless cycle of exile and return. When you cast Lumbering Battlement, its entry trigger exiles Abdel Adrian, Gorion's Ward, which in turn causes Touch the Spirit Realm to return from exile and immediately trigger to exile Lumbering Battlement right back. That departure brings Abdel Adrian, Gorion's Ward back to the battlefield to swallow up Touch the Spirit Realm along with any other nonland permanents you wish to bring along for the ride, and the cycle repeats indefinitely.
