Diregraf Horde + Deadeye Navigator + Ashnod's Altar + Signpost Scarecrow

Diregraf Horde

Deadeye Navigator

Ashnod's Altar

Signpost Scarecrow

How it works

1. Activate Diregraf Horde by paying 1, blinking it.
2. When Diregraf Horde enters the battlefield, it and Deadeye Navigator's soulbond ability triggers.
3. Resolve the Deadeye Navigator trigger, repairing it and Diregraf Horde.
4. Resolve the Diregraf Horde trigger, creating two 2/2 Zombie creature tokens.
5. Activate Ashnod's Altar twice by sacrificing the Zombies, adding CCCC.
6. Activate Signpost Scarecrow by paying 2, adding .
7. Repeat.

This loop centers on the endless flicker made possible by Deadeye Navigator paired with Diregraf Horde, using the soulbond ability to continuously re-pair them as the Horde enters the battlefield. Each time the Horde blinks, its entry triggers the creation of two decayed Zombie creature tokens, providing fresh fodder to feed into Ashnod's Altar for colorless mana. To sustain the blue mana required for Deadeye Navigator's flicker ability, Signpost Scarecrow steps in to filter some of that colorless bounty into any color you need.
