Esix, Fractal Bloom

Timestream Navigator

Ant Queen

How it works

1. Activate Ant Queen by paying 1, causing you to create a token copy of Timestream Navigator due to Esix.
2. If you don't have the city's blessing, the Timestream Navigator token gives you the city's blessing.
3. Activate the oldest Timestream Navigator by paying 2, tapping it and putting it from the battlefield onto the bottom of your library, causing you to take an extra turn after this one.
4. Repeat each turn.
