Evolution Witness + Jukai Preserver + Crystalline Crawler + Zirda, the Dawnwaker

Evolution Witness

Jukai Preserver

Crystalline Crawler

Zirda, the Dawnwaker

How it works

1. Activate Jukai Preserver by paying and discarding it, putting a +1/+1 counter on Crystalline Crawler and Evolution Witness.
2. Evolution Witness triggers, returning Jukai Preserver from your graveyard to your hand.
3. Activate Crystalline Crawler's first ability by removing a +1/+1 counter from it, adding .
4. Repeat.

This clever loop relies on Zirda, the Dawnwaker to slash the activation cost of Evolution Witness down to just {G}, making its adapt ability remarkably cheap to trigger. By discarding Jukai Preserver, you place +1/+1 counters that simultaneously trigger Evolution Witness to return the Preserver back to your hand and feed Crystalline Crawler's mana-producing ability. Crystalline Crawler then fuels the process by converting its counters into the green mana needed to repeat the entire cycle, generating infinite triggers.
