Esix, Fractal Bloom + Timestream Navigator + Legion Warboss

Esix, Fractal Bloom

Timestream Navigator

Legion Warboss

How it works

1. At the beginning of your combat step, Legion Warboss triggers, creating a copy of Timestream Navigator and giving it haste until end of turn.
2. Activate the Timestream Navigator token, 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.
