Deadeye Navigator + Charming Scoundrel + Bard, King of Dale

Deadeye Navigator

Charming Scoundrel

Bard, King of Dale

How it works

1. Activate Charming Scoundrel by paying 1, blinking it.
2. When Charming Scoundrel enters, it and Deadeye Navigator's soulbond ability trigger
3. Resolve the Deadeye Navigator trigger, repairing it and Charming Scoundrel.
4. Resolve the Charming Scoundrel trigger, creating two Treasure tokens.
5. Activate both Treasures by tapping and sacrificing them, adding 1.
6. Repeat.

This looping engine relies on the interplay between Deadeye Navigator and Charming Scoundrel to continuously trigger entry-the-battlefield effects by blinking the Scoundrel back into play. Because Bard, King of Dale is present to double any tokens created under your control, Charming Scoundrel's treasure generation mode produces twice as many Treasure tokens as normal. Sacrificing those doubled Treasures provides more than enough mana to pay for Deadeye Navigator's blink ability, keeping the loop going indefinitely and generating an endless supply of artifact and creature triggers.
