Esix, Fractal Bloom

Timestream Navigator

Assemble the Legion

How it works

1. At the beginning of your upkeep, Assemble the Legion triggers, putting a muster counter on itself and creating a copy of Timestream Navigator with haste for each Muster counter on Assemble the Legion.
2. Activate a copy of Timestream Navigator, paying 2 and putting Timestream Navigator on the bottom of your library to take an extra turn after this one.
3. Pass the turn.
4. Repeat.
