Niko, Light of Hope + Timestream Navigator + The Mighty Thor, Jane Foster

Niko, Light of Hope

Timestream Navigator

The Mighty Thor, Jane Foster

How it works

1. Activate Niko by paying 2 and tapping it, exiling Timestream Navigator and causing Shards you control to become a copy of Timestream Navigator until the end step.
2. Activate a Shard by paying 2, tapping it and putting it from the battlefield onto the bottom of your library, causing you to take an extra turn after this one.
3. At the beginning of the next end step, Timestream Navigator is returned from exile to the battlefield. The Mighty Thor then triggers, blinking Niko.
4. When Niko enters, it triggers, creating two Shard tokens.
5. Repeat each turn.
