Esika's Chariot + There and Back Again + Time Sieve Combo

All permanents on the battlefield.

There and Back Again has exactly two lore counters on it. An opponent cannot block and kill Esika's Chariot.

At the beginning of your precombat main phase, There and Back Again triggers, putting a lore counter on it.

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.

Activate Esika's Chariot's crew ability by tapping the Smaug token, causing Esika's Chariot to become an artifact creature until end of turn.

Declare Esika's Chariot as an attacker.

Esika's Chariot's second ability triggers, creating a copy of the Smaug token.

Put either Smaug token into your graveyard due to the legend rule.

When the Smaug token dies, it triggers, creating fourteen Treasure tokens.

Activate Time Sieve by tapping it and sacrificing five Treasures, causing you to take an extra turn after this one.

Repeat from step 3 each turn.
