Deadeye Navigator + Precursor Golem + Phyrexian Altar

Deadeye Navigator

Precursor Golem

Phyrexian Altar

How it works

1. Activate Precursor Golem by paying 1, blinking it.
2. When Precursor Golem enters the battlefield, it and Deadeye Navigator's soulbond ability trigger.
3. Resolve the Deadeye Navigator trigger, repairing it and Precursor Golem.
4. Resolve the Precursor Golem, creating two 3/3 Golem artifact creature tokens.
5. Activate Phyrexian Altar twice by sacrificing the Golems, adding 1.
6. Repeat.

By bonding Deadeye Navigator to Precursor Golem, you gain the ability to repeatedly flicker the Golem for just two mana. Every time Precursor Golem re-enters the battlefield, it triggers to bring along a fresh supply of two 3/3 Golem artifact creature tokens. You can then feed those newly spawned tokens directly into Phyrexian Altar, sacrificing them to easily generate the blue and colorless mana needed to fuel the next blink and keep the loop running indefinitely.
