The 3 combo pieces

What must be in place

Deadeye Navigator is paired with Dutiful Replicator.
There and Back Again has exactly two lore counters on it.

How to execute it

  1. At the beginning of your precombat main phase, There and Back Again triggers, putting a lore counter on it.
  2. There and Back Again's third chapter ability triggers, creating a legendary 6/6 Smaug creature token and causing you to sacrifice There and Back Again.
  3. Activate Dutiful Replicator by paying {1}{U}, blinking it.
  4. When Dutiful Replicator enters the battlefield, it and Deadeye Navigator's soulbond ability trigger.
  5. Resolve the Deadeye Navigator trigger, repairing it and Dutiful Replicator.
  6. Resolve the Dutiful Replicator trigger, causing you to pay {1} to create a copy of the Smaug token.
  7. Put one of the Smaug tokens into your graveyard due to the legend rule.
  8. When the Smaug dies, it triggers, creating fourteen Treasure tokens.
  9. Activate three Treasures by tapping and sacrificing them, adding {2}{U}.
  10. Repeat from step 3.
  11. Once you have infinite mana, you may instead target any other token you control using Dutiful Replicator's ability.
