Forerunner of the Coalition + Timestream Navigator + Deadeye Navigator

Forerunner of the Coalition

Timestream Navigator

Deadeye Navigator

How it works

1. Activate Timestream Navigator by paying 2, tapping and putting it on the bottom of your library, causing you to take an extra turn after this one.
2. Activate Forerunner of the Coalition using its ability from Deadeye Navigator by paying 1, blinking Forerunner of the Coalition.
3. Forerunner of the Coalition enters, triggering its first ability and Deadeye Navgiator's soulbond ability.
4. Resolve Forerunner of the Coalition's ability, causing you to search your library for Timestream Navigator and put it on top of your library.
5. Resolve Deadeye Navigator's soulbond ability, pairing it with Forerunner of the Coalition.
6. Move to your next turn, drawing Timestream Navigator during your draw phase.
7. Cast Timestream Navigator by paying 1.
8. Timestream Navigator enters the battlefield, triggering Forerunner of the Coalition's second ability, causing each opponent to lose 1 life.
9. Repeat.

This loop relies on the soulbond ability of Deadeye Navigator to continuously reset your board state, turning its flicker effect into an engine fueled by mana and your deck's architecture. By activating Timestream Navigator and securing the city's blessing, you can take infinite extra turns, but you need a way to find it and replay it repeatedly. That's where Forerunner of the Coalition shines: every time it enters the battlefield via Deadeye Navigator's exile ability, its first ability lets you tutor Timestream Navigator straight back to the top of your library to draw on your new turn, while its second ability drains your opponents' life away with each iteration.
