Diregraf Horde + Deadeye Navigator + Ashnod's Altar + Stonework Packbeast

Diregraf Horde

Deadeye Navigator

Ashnod's Altar

Stonework Packbeast

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 Stonework Packbeast by paying 2, adding .
7. Repeat.

By bonding Deadeye Navigator to Diregraf Horde, you gain the ability to continually blink the Horde to flood the board with decayed Zombie tokens. Those tokens are then fed directly into Ashnod's Altar to generate a massive supply of colorless mana. To keep the loop going indefinitely, you can funnel some of that mana through Stonework Packbeast to pay the precise blue activation cost required by Deadeye Navigator, turning your sacrifices into an endless engine of mana, tokens, and blinks.
