Hazel of the Rootbloom + Time Sieve + There and Back Again

Hazel of the Rootbloom

Time Sieve

There and Back Again

How it works

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. At the beginning of your end step, Hazel of the Rootbloom triggers, creating a copy of the Smaug token.
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 Time Sieve by tapping it and sacrificing five Treasures, causing you to take an extra turn after this one.
7. Repeat from step 3 each turn.
