Esix, Fractal Bloom

Timestream Navigator

Goblin Assault

How it works

1. At the beginning of your upkeep, Goblin Assault triggers, creating a copy of Timestream Navigator with haste.
2. Activate any 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.
