Fertilid + Amulet of Vigor + Nissa, Resurgent Animist + Thranduil's Company

Fertilid

Amulet of Vigor

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 Amulet of Vigor.
2. When the basic land enters, Amulet of Vigor, Nissa and Thranduil's Company trigger.
3. Resolve the Amulet of Vigor 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 intricate engine turns a modest Elemental into a boundless source of mana and land-searching momentum. The magic truly begins with Amulet of Vigor, which ensures that every basic land fetched by Fertilid arrives and immediately untaps to help pay for the next activation. Meanwhile, Nissa, Resurgent Animist converts those incoming lands into a steady stream of green mana, while Thranduil's Company continuously replenishes Fertilid's vanished resources by stacking fresh +1/+1 counters back onto it with each landfall.
