Cast Planar Incision by paying its mana cost, blinking Abdel Adrian.
Abdel Adrian leaves the battlefield, returning Possessed Skaab and all other cards that were exiled with it to the battlefield.
Abdel Adrian and Possessed Skaab trigger.
Resolve the Possessed Skaab trigger, returning Planar Incision from your graveyard to your hand.
Holding priority, activate any number of nonland permanents you control by tapping them, adding at least enough mana to cast Planar Incision.
Resolve the Abdel Adrian trigger, exiling Possessed Skaab and the mana-producing permanents until Abdel Adrian leaves the battlefield, and creating a 1/1 Soldier creature token for each permanent exiled this way.
Repeat.
This loop is a masterclass in recursive value, centering on Abdel Adrian, Gorion's Ward to continuously reset your board. When you cast Planar Incision to blink Abdel Adrian, it triggers his exile-and-token-creation ability while letting Possessed Skaab return from your graveyard to yours, using its enter-the-battlefield trigger to bring Planar Incision right back to your hand. Meanwhile, Possessed Skaab's own static replacement effect is neatly bypassed because Abdel Adrian's exile effect handles sending it away instead of letting it die. By tucking your mana-producing permanents into Abdel Adrian's exile zone along with the Skaab, you can tap them for mana before they vanish and loop the entire sequence indefinitely for infinite tokens, triggers, and blinks.
