Simian Simulacrum + Crystalline Crawler + Deadeye Navigator

Simian Simulacrum

Crystalline Crawler

Deadeye Navigator

How it works

1. Activate Simian Simulacrum by paying 1, blinking it.
2. Simian Simulacrum enters the battlefield, triggering itself and Deadeye Navigator's soulbond ability.
3. Resolve the Simian Simulacrum trigger, putting two +1/+1 counters on Crystalline Crawler.
4. Resolve the Deadeye Navigator trigger, repairing it and Simian Simulacrum.
5. Activate Crystalline Crawler's first ability twice by removing two +1/+1 counters from it, adding 1.
6. Repeat.
