This sparkling loop centers around Deadeye Navigator pairing up via soulbond with Charming Scoundrel, granting the Scoundrel a reliable blink ability that resets its entry triggers. When Charming Scoundrel enters the battlefield, its chosen mode creates a Treasure token, an output that is immediately doubled into a pair of tokens thanks to the powerful replacement effect of Mondrak, Glory Dominus. Sacrificing those two resulting Treasures provides more than enough mana to pay for Deadeye Navigator's blink cost, keeping the engine running indefinitely.
