Deadeye Navigator + Blessed Sanctuary + Phyrexian Altar + Anointed Procession

Deadeye Navigator

Blessed Sanctuary

Phyrexian Altar

Anointed Procession

How it works

1. Activate Deadeye Navigator by paying 1, 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 two 2/2 Unicorn creature tokens.
5. Activate Phyrexian Altar twice by sacrificing the Unicorns, adding 1.
6. Repeat.

This elegant engine starts by using Deadeye Navigator's soulbond ability to pair with an available creature, granting both the classic blink activation that feeds the loop. As you flicker pieces in and out, Blessed Sanctuary acts as the token factory, turning every creature's entry into a pair of 2/2 Unicorns—a number that Anointed Procession happily doubles into a quadrupled army. Meanwhile, Phyrexian Altar is right there in the background to harvest those sacrifices for the exact blue and colorless mana you need to pay for Deadeye Navigator's next blink, keeping the loop running infinitely.
