Abdel Adrian enters the battlefield, exiling Sakashima of a Thousand Faces until Abdel Adrian leaves the battlefield, and creating a 1/1 Soldier creature token.
Sakashima of a Thousand Faces leaves the battlefield, triggering its second ability, returning Wormfang Drake from exile to the battlefield.
Wormfang Drake enters the battlefield, triggering its first ability, exiling Abdel Adrian.
Abdel Adrian leaves the battlefield, returning Sakashima of a Thousand Faces from exile to the battlefield as a copy of Wormfang Drake.
Sakashima of a Thousand Faces enters the battlefield, triggering its first ability, exiling Wormfang Drake.
Wormfang Drake leaves the battlefield, triggering its second ability, returning Abdel Adrian from exile to the battlefield.
Repeat from step 2.
This clever loop turns a modest dragon and a legendary rogue into an infinite engine, powered entirely by Abdel Adrian, Gorion's Ward cycling in and out of the battlefield. Because Sakashima of a Thousand Faces ignores the legend rule and enters as a copy of Wormfang Drake, it cleverly bypasses the sacrifice penalty by exiling Abdel Adrian instead. Each iteration of this sequence feeds on itself: Abdel Adrian's exile triggers return Wormfang Drake, which in turn drops Abdel Adrian right back onto the board to generate a boundless army of Soldier tokens and endless enter-the-battlefield triggers.
