Timestream Navigator + Endless Evil + Lightning Greaves

Timestream Navigator

Endless Evil

Lightning Greaves

How it works

1. At the beginning of your upkeep, Endless Evil triggers, creating a token copy of Timestream Navigator.
2. If you do not have the city's blessing, both Timestream Navigator's ascend abilities trigger, giving you the city's blessing.
3. Activate Lightning Greaves' equip ability by paying 0, attaching it to the Timestream Navigator token.
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.
