The 3 combo pieces

What must be in place

Romana II does not have summoning sickness.
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 Romana II by paying {1} and tapping it, creating a token copy of Smaug with haste.
  4. Put either Smaug token into your graveyard due to the legend rule.
  5. When the Smaug token dies, it triggers, creating fourteen Treasure tokens.
  6. Activate three Treasures by tapping and sacrificing them, adding {3}.
  7. Activate Romana II by paying {3} and untapping it, giving it +2/+2 until end of turn.
  8. Repeat from step 3.
