Solitary Sanctuary + Crystalline Crawler + Vedalken Certarch + Freed from the Real

Solitary Sanctuary

Crystalline Crawler

Vedalken Certarch

Freed from the Real

How it works

1. Activate Vedalken Certarch by tapping it, tapping a creature an opponent controls.
2. Solitary Sactuary triggers, putting a +1/+1 counter on Crystalline Crawler.
3. Activate Crystalline Crawler's first ability by removing a +1/+1 counter from it, adding .
4. Activate Freed from the Real's second ability by paying , untapping Vedalken Certarch.
5. Repeat.
6. You may also repeat this loop during each turn.

This intricate loop locks down your opponents' boards by leveraging Vedalken Certarch to repeatedly tap down their creatures, provided you have three or more artifacts to satisfy its metalcraft condition. Each time that tap happens, Solitary Sanctuary triggers to place a +1/+1 counter onto Crystalline Crawler. You can immediately cash in that newly minted counter using Crystalline Crawler's ability to generate the blue mana required by Freed from the Real, which untaps Vedalken Certarch to do it all over again.
