Tanazir Quandrix

Deadeye Navigator

Crystalline Crawler

How it works

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