Inalla, Archmage Ritualist + Timestream Navigator + Thassa, Deep-Dwelling

Inalla, Archmage Ritualist

Timestream Navigator

Thassa, Deep-Dwelling

How it works

1. At the beginning of your end step, Thassa triggers, blinking Timestream Navigator.
2. If you don't have the city's blessing, Timestream Navigator's Ascend ability gives you the city's blessing.
3. When Timestream Navigator enters the battlefield, triggering Inalla, causing you to pay 1 to create a token copy of Timestream Navigator with haste.
4. Activate the Timestream Navigator token by paying 2, tapping it, and putting it on the bottom of your library, causing you to take an extra turn after this one.
5. Repeat each turn.
