Deadeye Navigator + Blessed Sanctuary + Ashnod's Altar + Mycosynth Lattice

Deadeye Navigator

Blessed Sanctuary

Ashnod's Altar

Mycosynth Lattice

How it works

1. Activate Deadeye Navigator by paying 2, blinking it.
2. When Deadeye Navigator enters the battlefield, its soulbond ability and Blessed Sanctuary triggers.
3. Resolve the Deadeye Navigator trigger, pairing it and another creature you control.
4. Resolve the Blessed Sanctuary trigger, creating a 2/2 Unicorn creature token.
5. Activate Ashnod's Altar by sacrificing the Unicorn, adding 2.
6. Repeat.

This loop uses the mana generated by Ashnod's Altar to fuel Deadeye Navigator's blink ability, but the engine only succeeds because of the supporting pieces. Mycosynth Lattice turns everything colorless and acts as a universal enabler, while Blessed Sanctuary ensures that every time your creature re-enters the battlefield, it floods the board with a fresh 2/2 white Unicorn creature token to feed back into the altar.
