Phylath, World Sculptor + Fertilid + Crystalline Crawler + Ancient Greenwarden + Xenograft

Phylath, World Sculptor

Fertilid

Crystalline Crawler

Ancient Greenwarden

Xenograft

How it works

1. Activate Fertilid by paying 1 and removing a +1/+1 counter from it, causing you to search your library for a basic land card and put it onto the battlefield tapped.
2. When the land enters the battlefield, Phylath's second ability triggers twice, putting four +1/+1 counters on Fertilid and Crystalline Crawler.
3. Activate Crystalline Crawler's first ability twice by removing two +1/+1 counters from it, adding 1.
4. Repeat.

This delightful loop turns the humble Plant synergy of Phylath, World Sculptor into an engine that strips your entire library of basic lands. The secret ingredient is Xenograft, which ensures that Fertilid and Crystalline Crawler count as Plants so that Phylath's landfall ability can continuously refuel them. Meanwhile, Ancient Greenwarden doubles those landfall triggers, generating twice as many +1/+1 counters as you need to keep the cycle going. As Fertilid fetches lands and Crystalline Crawler converts counters into the mana needed to activate the search, this web of triggers floods your board with every basic land your deck has to offer.
