Fertilid + Tiller Engine + Nissa, Resurgent Animist + Thranduil's Company

Fertilid

Tiller Engine

Nissa, Resurgent Animist

Thranduil's Company

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 on the battlefield untapped due to Tiller Engine.
2. When the basic land enters, Tiller Engine, Nissa and Thranduil's Company trigger.
3. Resolve the Tiller Engine trigger, untapping the basic land.
4. Resolve the Nissa trigger, adding .
5. Resolve the Thranduil's Company trigger, putting two +1/+1 counters on Fertilid.
6. Activate the basic land by tapping it, adding 1.
7. Repeat.

This delightful loop turns simple land drops into a self-sustaining engine by cycling resources between Fertilid and the rest of your board. Every time Fertilid fetches a basic land from your library, Tiller Engine immediately untaps it so you can tap it for mana, while Nissa, Resurgent Animist refunds the mana cost to keep the chain moving. Meanwhile, Thranduil's Company continuously replenishes Fertilid's +1/+1 counters with its landfall ability, ensuring you never run out of fuel as you pull every basic land straight out of your deck.
